| CVE-2026-72312 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.9 High |
| In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: fix VF bringup affecting PF promiscuous state Mbox handling of nix_set_rx_mode for a VF with promiscuous and all_multi flags set to false causes deletion of the PF's promiscuous and allmulti MCAM rules. This occurs because the APIs that enable/disable these rules operate only on the PF, even when the mbox request is made via a VF interface. Guard both rvu_npc_enable_allmulti_entry() and rvu_npc_enable_promisc_entry() disable paths with an is_vf() check so that a VF bringing up or tearing down its interface cannot inadvertently clear the PF's MCAM rules. | ||||

| CVE-2026-72302 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc3-control: Use overflow checks in control_update size calc In sof_ipc3_control_update(), the expected_size calculation uses firmware-provided cdata->num_elems in arithmetic that could overflow on 32-bit platforms, wrapping to a small value. This would allow the cdata->rhdr.hdr.size comparison to pass with mismatched sizes, potentially leading to out-of-bounds access in snd_sof_update_control. Use check_mul_overflow() and check_add_overflow() to detect and reject overflowed size calculations. | ||||
| CVE-2026-72301 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc3-control: Fix TOCTOU in bytes_put and bytes_get In sof_ipc3_bytes_put(), the size used for the memcpy is derived from the old data->size already in the buffer, not the incoming new data's size field. If the new data has a different size, the copy length is wrong: it may truncate valid data or copy stale bytes. Similarly, sof_ipc3_bytes_get() checks data->size against max_size without accounting for the sizeof(struct sof_ipc_ctrl_data) offset of the flex array within the allocation. Fix bytes_put to validate and use the incoming data's sof_abi_hdr.size from ucontrol before copying. Fix bytes_get to subtract sizeof(*cdata) from the bounds check to match the actual available space. | ||||

| In the Linux kernel, the following vulnerability has been resolved: tipc: restrict socket queue dumps in enqueue tracepoints tipc_sk_enqueue() runs with sk->sk_lock.slock held while the socket is owned by user context. The spinlock protects the backlog queue in this path, but it does not serialize against the socket owner consuming or purging sk_receive_queue.

| CVE-2026-72297 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: net: atm: reject out-of-range traffic classes in QoS validation Reject ATM traffic classes above ATM_ANYCLASS in check_tp(). SO_ATMQOS stores the supplied QoS after check_qos() succeeds, so accepting larger values leaves invalid traffic_class values in vcc->qos. That bad state later reaches pvc_info(), which indexes class_name[] with vcc->qos.{rx,tp}.traffic_class. Values above ATM_ANYCLASS cause an out-of-bounds read when /proc/net/atm/pvc is read. Tighten the existing QoS validation so invalid traffic_class values are rejected at the point where user supplied QoS is accepted. | ||||
| CVE-2026-72296 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 9.1 Critical |
| In the Linux kernel, the following vulnerability has been resolved: net: ife: require ETH_HLEN to be pullable in ife_decode() ife decode may return after making only the outer IFE header and metadata pullable. The caller then passes the decapsulated packet to eth_type_trans(), which expects the inner Ethernet header to be accessible from the linear data area. With a malformed IFE frame, the inner Ethernet header may still be shorter than ETH_HLEN in the linear area, which can lead to a crash in the original code. Fix this by extending the pull check in ife_decode() so that the inner Ethernet header is also guaranteed to be pullable before returning. | ||||
| CVE-2026-72295 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Validate irqchip index in irqfd routing Sashiko reported that the irqchip index is not validated for LoongArch. Add validation and reject out-of-range irqchip indexes to avoid indexing past the routing table's chip array. | ||||
| CVE-2026-72291 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 9.3 Critical |
| In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix unlikely race in try_get_locked_pte() Fix an unlikely race in try_get_locked_pte(), which could have happened if puds or pmds get unmapped between the p?dp_get() and p?d_offset() functions. | ||||
| CVE-2026-72289 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 9.3 Critical |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic: Check the interrupt is still ours before migrating it vgic_prune_ap_list() drops both ap_list_lock and irq_lock while migrating an interrupt to another vCPU. After reacquiring the locks it only checks that the affinity is unchanged (target_vcpu == vgic_target_oracle(irq)) before moving the interrupt, which assumes that an interrupt whose affinity is preserved is still queued on this vCPU's ap_list. That assumption no longer holds if the interrupt is taken off the ap_list while the locks are dropped. vgic_flush_pending_lpis() removes the interrupt from the list and sets irq->vcpu to NULL, but leaves enabled/pending/target_vcpu untouched. As the interrupt is still enabled and pending, vgic_target_oracle() returns the same target_vcpu, so the affinity check passes and list_del() is run a second time on an entry that has already been removed. Also check that the interrupt is still assigned to this vCPU (irq->vcpu == vcpu) before moving it. | ||||
| CVE-2026-72288 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 9.3 Critical |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic: Handle race between interrupt affinity change and LPI disabling Hyunwoo Kim reports some really bad races should the following situation occur: - LPI-I is pending in vcpu-B's AP list - vcpu-A writes to vcpu-B's RD to disable its LPIs - vcpu-C moves I from B to C If the last two race nicely enough, vgic_prune_ap_list() can drop the irq and AP list locks, reacquire them, and in the interval the irq has been freed. UAF follows. The fix is two-fold: - Before dropping the irq and ap_list locks, take a reference on the irq - Do not try to handle migration of the pending bit: there is no expectation that this state is retained, as per the architecture With that, we're sure that the interrupt is still around, and we safely remove it from the AP list as it has no target at this stage (unless another interrupt fires, but that's another story). | ||||
| CVE-2026-72287 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: nVMX: Move vTPR vs. TPR Threshold consistency check into "normal" checks Move the off-by-default consistency check for vmcs12.tpr_threshold vs. the virtual APIC vTPR into the "normal" controls checks, as waiting until KVM has loaded some amount of state is unnecessary and actively dangerous. Specifically, failure to unwind vmcs01.GUEST_CR3 to KVM's value when EPT is disabled results in KVM running L1 with an L1-controlled CR3, not with KVM's CR3! Alternatively, KVM could simply reset the MMU to force a reload of vmcs01.GUEST_CR3, but the _only_ reason the check was shoved into a "late" flow was to wait until the vmcs12 pages were retrieved. Rather than build up more crusty code, simply access vTPR using a regular guest memory access (performance isn't a concern). To circumvent the restrictions that led to KVM deferring nested_get_vmcs12_pages(), (a) use a VM-scoped API to read guest memory so that it always hits non-SMM memslots (for RSM), and (b) skip the check (since its off-by-default anyways) when the vCPU doesn't want to run, i.e. when userspace is restoring/stuffing state. If reading guest memory fails, simply skip the consistency check, as KVM's de facto ABI is that VMX instruction accesses to non-existent memory get PCI Bus Error semantics, where reads return 0xFFs. And if vTPR=0xFF, then the vTPR is guaranteed to be greater than or equal to TPR_THRESHOLD. | ||||
| CVE-2026-72286 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Do not allow intra-host migration/mirroring of SNP VMs The intra-host migration/mirroring feature is not fully implemented for SEV-SNP VMs. The proper migration requires additional SNP-specific state such as guest_req_mutex, guest_req_buf, and guest_resp_buf to be transferred or initialized on the destination. The SNP VM mirroring requires vmsa features to be copied as well otherwise ASID would be bound to SNP range while VM is detected as a SEV VM. Reject SNP source VMs in migration/mirroring until proper SNP state transfer is implemented. [sean: let lines poke past 80 chars, tag for stable] | ||||
| CVE-2026-72284 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Ignore pending PV EOI if the vCPU has since disabled PV EOIs Ignore KVM's internal "service pending PV EOI" request if the vCPU has disabled PV EOIs since the request was made. Asserting that PV EOIs are enabled can fail if reading guest memory in pv_eoi_get_user() fails, i.e. if pv_eoi_test_and_clr_pending() bails early, *and* the vCPU also disables PV EOIs. kernel BUG at arch/x86/kvm/lapic.c:3338!

| CVE-2026-72282 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: Move kvm_io_bus_get_dev() locking responsibilities to callers kvm_io_bus_get_dev() returns a device that is only matched by the address, and nothing else. This can cause a lifetime issue if the matched device is not the expected type, as by the time the caller can introspect the object, it might be gone (the srcu lock having been dropped). Given that there is only a single user of this helper, the simplest option is to move the locking responsibility to the caller, which can keep the srcu lock held for as long as it wants. Note that this aligns with other kvm_io_bus*() helpers, which already require the srcu lock to be held by the callers. | ||||
| CVE-2026-72280 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Drop bogus WARN for write to ZCR_EL2 It is entirely possible for a guest to write to the ZCR_EL2 sysreg alias while in a nested context, as it is expected if FEAT_NV2 is advertised to the L1 hypervisor. Get rid of the bogus WARN which, since the hyp vectors were installed at this point, has the effect of a hyp_panic... | ||||
| CVE-2026-72279 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 9 Critical |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Respect read-only PFN when mapping L1 VNCR KVM currently maps the L1 VNCR into the host stage-1 by relying entirely on the permissions of the guest stage-1. At the same time, it is entirely possible that the backing PFN is read-only (e.g. RO memslot), meaning that the L1 VNCR should use at most a read-only mapping. Cache the writability of the PFN in the VNCR TLB and use it to constrain the resulting fixmap permissions. Promote VNCR permission faults to an SEA in the case where the guest attempts to write to a read-only endpoint. Conveniently, this also plugs a page leak found by Sashiko [*] resulting from the early return for a read-only PFN. | ||||
| CVE-2026-72278 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 9.3 Critical |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Re-translate VNCR before injecting abort KVM faults in the VNCR page with FOLL_WRITE whenever the guest aborts for a write, similar to how a regular stage-2 mapping is handled. It is entirely possible that the guest reads from the VNCR before writing to it, in which case the PFN could only be read-only. Invalidate the VNCR TLB and re-fetch the translation upon taking a VNCR abort, allowing the host mapping to be faulted in for write the second time around. Interestingly enough, this also satisfies the ordering requirements of FEAT_ETS2/3 between descriptor updates and MMU faults. | ||||
| CVE-2026-72277 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 9.3 Critical |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Inject SEA if guest VNCR isn't normal memory When constructing an L1 VNCR mapping, KVM unconditionally uses cacheable memory attributes, even if the underlying PFN isn't memory. This gets particularly hairy if the endpoint doesn't support cacheable memory attributes, potentially throwing an SError on writeback... While KVM does permit cacheable memory attributes on certain PFNMAP VMAs, kvm_translate_vncr() isn't currently grabbing the VMA. So do the simpler thing for now and just reject everything that isn't memory. | ||||
| CVE-2026-72262 | 1 Linux | 1 Linux Kernel | 2026-08-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc3-control: Fix heap overflow in bytes_ext put/get The ipc_control_data buffer is allocated as kzalloc(max_size), where max_size covers the entire struct sof_ipc_ctrl_data including its flexible array payload. However, the bounds checks in bytes_ext_put and _bytes_ext_get compared user data lengths against max_size directly, ignoring that cdata->data sits at an offset of sizeof(struct sof_ipc_ctrl_data) bytes into the allocation. This allowed writing up to sizeof(struct sof_ipc_ctrl_data) bytes past the end of the heap buffer from unprivileged userspace via the ALSA TLV kcontrol interface, and similarly allowed over-reading adjacent heap data on the get path. Fix all bounds checks to subtract sizeof(*cdata) from max_size so they reflect the actual space available at the cdata->data offset. Also fix the error-path restore in bytes_ext_put which wrote to cdata->data instead of cdata, causing the same overflow. | ||||
