| In the Linux kernel, the following vulnerability has been resolved:
ipvs: avoid out-of-bounds write in ip_vs_nat_icmp
Sashiko warns that local attacker can modify the packet
while it is processed by IPVS. Some places read the
IP ihl field multiple times which can cause out-of-bounds
access. One such place is ip_vs_nat_icmp where we
can write after the validated area.
Fix it by providing ciph argument just like it is done for
IPv6 and use ciph->len as offset to the embedded transport
header.
Modify some IPv4 header checks by reading the ihl field
only once. |
| In the Linux kernel, the following vulnerability has been resolved:
xdp: reject clones that overrun skb_shared_info tailroom
xdpf_clone() clones broadcast copies into a single page and sets
frame_sz to PAGE_SIZE. __xdp_build_skb_from_frame() later treats that
page like a normal XDP frame and expects the usual skb_shared_info
tailroom at the end of the buffer.
The current check only rejects frames whose linear xdp_frame header,
headroom, and packet data exceed PAGE_SIZE. A source frame backed by a
larger allocation can still satisfy that check while extending into the
clone's required shared-info area. When such a clone is converted back
into an skb, build_skb_around() places skb_shared_info over live packet
bytes and later writes can corrupt XDP return metadata.
Reject clones unless their linear area fits inside
SKB_WITH_OVERHEAD(PAGE_SIZE), matching the tailroom requirement already
enforced by the XDP-to-skb conversion path. |
| In the Linux kernel, the following vulnerability has been resolved:
ip6_tunnel: clear skb2->cb[] in ip6ip6_err()
ip6ip6_err() clones an outer IPv6 ICMP error skb, pulls it to the
quoted inner IPv6 packet, and then passes the clone to icmpv6_send().
The clone still carries the outer packet's inet6_skb_parm in skb->cb.
If the outer packet had a Home Address Option, IP6CB(skb2)->dsthao
remains non-zero after skb_pull(). icmpv6_send() later calls
mip6_addr_swap(), which uses that stale dsthao offset against the quoted
inner packet. A malformed inner destination-options header can then make
the HAO lookup and address swap run past the end of the quoted packet
and corrupt skb_shared_info.
Clear skb2->cb[] before pulling the quoted inner IPv6 packet so the
reply path does not reuse metadata left by the outer IPv6 stack. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usx2y: bound the hwdep mmap fault offset
snd_us428ctls_vm_fault() turns the faulting page offset into a kernel
address with no bound of any kind:
offset = vmf->pgoff << PAGE_SHIFT;
vaddr = (char *)(...)->us428ctls_sharedmem + offset;
page = virt_to_page(vaddr);
get_page(page);
vmf->page = page;
return 0;
snd_us428ctls_mmap() checks only the length of the mapping, never the
offset, and us428ctls_sharedmem is a single page from
alloc_pages_exact(). For a character device file_mmap_size_max()
returns ULONG_MAX, so the mm layer imposes no ceiling either. Every page
offset above zero resolves to a struct page outside the object, and the
handler installs it into the caller's address space read-write; the vma
is not marked read-only.
The caller picks the page frame with a single mmap() argument and gets
read-write access to a page of kernel memory it does not own; an offset
that lands in an unpopulated vmemmap region oopses instead.
A process that can open the hwdep node of an attached US-X2Y reaches
this after loading the FPGA image through the same node; no capability
check is involved.
On 7.2.0-rc5 (arm64), mmap() with a large offset:
Unable to handle kernel paging request at virtual address fffffdffc45d5ac8
pc : snd_us428ctls_vm_fault+0x68/0x140 [snd_usb_usx2y]
Call trace:
snd_us428ctls_vm_fault+0x68/0x140 [snd_usb_usx2y]
__do_fault
__handle_mm_fault
handle_mm_fault
el0_da
Reject any offset outside the shared region. The pcm hwdep handler in
usx2yhwdeppcm.c computes its address the same way and needs the same
bound.

| In the Linux kernel, the following vulnerability has been resolved:
ipvs: clear IPv4 options after rebasing tunnel ICMP errors
ip_vs_in_icmp() rebases an skb from the outer ICMP packet to the
quoted original request before passing it to icmp_send(). However,
IPCB(skb)->opt still describes the outer IPv4 header.
A timestamp option in the outer header can therefore leave an offset
that points into the quoted transport header after the rebase.
__ip_options_echo() treats a byte at that stale location as the option
length and copies it into the fixed-size option storage on the
__icmp_send() stack, causing a stack out-of-bounds write.
Clear the stale option metadata after resetting the network header.
Keep the remaining control block fields, including the ingress
interface used by the ICMP response path. |
| Wazuh is a free and open source platform used for threat prevention, detection, and response. From 3.9.0 until 4.14.5 and 5.0.0-beta2, the Wazuh cluster protocol in framework/wazuh/core/cluster/common.py allows an authenticated cluster node to exhaust memory on the master. The receive_str() method accepts an attacker-controlled total for InBuffer without a maximum, so a new_str command can request a multi-gigabyte bytearray and repeated requests accumulate in in_str. The divided-message path also retains flag_divided fragments under unique counters in div_msg_box without a count, aggregate-size, or expiration limit. Exploitation can disrupt agent connectivity and alert processing across the monitored environment. This issue is fixed in versions 4.14.5 and 5.0.0-beta2. |
| electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.11.11, electerm constructs operating system commands in src/app/lib/fs.js by interpolating untrusted file paths into the rmrf(), mv(), and cp() functions. A malicious SSH or SFTP server can provide a filename containing quote characters and shell metacharacters, and a victim can cause that filename to reach the affected operation during remote-to-local transfer, conflict renaming, copying, moving, or removal. The generated `rm -rf`, mv, `cp -r`, PowerShell Remove-Item, Move-Item, or Copy-Item command can then interpret the filename as shell syntax. This allows arbitrary command execution with the electerm desktop user's privileges on POSIX and Windows systems, enabling data exfiltration, file modification, malware installation, or denial of service. This issue is fixed in version 3.11.11. |
| A improper neutralization of special elements used in an os command ('os command injection') vulnerability in Fortinet FortiSandbox 4.4.0 through 4.4.8 may allow attacker to execute unauthorized code or commands via <insert attack vector here> |
| Improper Neutralization of Special Elements used in an OS Command in the package manager component of Black Duck blackduck-c-cpp before 3.0.7 allows an actor able to create a file within the scanned build directory to execute operating system commands as the account running the scan.
Filesystem paths encountered while traversing the scanned directory are interpolated into command strings that are executed through a shell without quoting or escaping, so shell metacharacters within those paths are interpreted rather than treated as literal text. No control over the build command or the tool's configuration is required. |
| Notepad++ is a free and open-source source code editor. Prior to 8.9.7, the expandNppEnvironmentStrs function in PowerEditor/src/WinControls/StaticDialog/RunDlg/RunDlg.cpp copies a Notepad++ variable name between $( and ) into the fixed-size wchar_t str[MAX_PATH] stack buffer without bounding the m loop index, allowing a name of 260 or more characters to corrupt adjacent stack data, terminate the process through __report_gsfailure, and potentially execute code. This issue is fixed in version 8.9.7. |
| Notepad++ is a free and open-source source code editor. Prior to 8.9.7, macros loaded from an attacker-controlled shortcuts.xml bypass the HMAC validation applied to UserDefinedCommands and can invoke Scintilla actions and the internal Open in Default Viewer command in an elevated Notepad++ process, allowing protected file modification and conditional elevated command execution when a local attacker influences settingsDir and a user triggers the macro. This issue is fixed in version 8.9.7. |
| 4MOSAn GCB Doctor developed by 4MOSAn Security Technology has a OS Command Injection vulnerability. Unauthenticated remote attackers can inject malicious commands through an unremoved ADOdb test page parameter, thereby executing arbitrary system commands on the server. |
| Sakura Editor provided by Sakura Editor Development Community contains an OS command injection vulnerability. If a victim user is directed to edit a file in a crafted directory, arbitrary OS command may be executed on the user's PC when the user invokes "Open Terminal". |
| Multiple DrayTek VigorAP models contain a command injection vulnerability in the setcamset function. The vulnerability is caused by insufficient filtering of the selectSlaves field before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface. |
| Multiple DrayTek VigorAP models contain a command injection vulnerability in the InquierTime function. The vulnerability is caused by insufficient filtering of the time field before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface. |
| An unauthenticated OS command injection vulnerability exists in the parental control functionality of Archer BE800 V1, BE3600 V1, and AX75 V1 due to improper filtering and neutralization of special characters in certain parameters. A LAN-based attacker can inject arbitrary commands and execute them with root privileges.
Successful exploitation may result in complete device compromise and impact the confidentiality, integrity, and availability of the affected device and network traffic. |
| An authenticated command injection vulnerability in TP-Link Archer BE800 V1 allows an attacker with administrative access to execute arbitrary system commands with root privileges by injecting shell metacharacters via a VPN connection.
Successful exploitation may enable persistent backdoors, credential theft, LAN reconnaissance, and router-assisted attacks against connected devices. |
| A stored OS
command injection vulnerability exists in the parent-control module of TP-Link
Archer BE3600 V1. An authenticated adjacent attacker with administrative access
may store a crafted profile name containing shell metacharacters, which is
later processed unsafely during daily cloud report generation and may result in
arbitrary command execution.
Successful
exploitation may allow command execution on the affected device with potential
impact to device confidentiality, integrity, and availability. |
| LibVNCClient is a library for easy implementation of a VNC client. In versions 0.9.12 through 0.9.15, a malicious (or man-in-the-middle) VNC server can force a connecting `libvncclient` to write attacker-controlled data past the end of its framebuffer. This is an out-of-bounds heap write with attacker-controlled length, contents, and offset. It needs no authentication (the attacker
is the server), works in a default build with default settings, and fires from a single `FramebufferUpdate` the moment the victim connects. It crashes any client unconditionally (denial of service); we also demonstrated it overwriting an application callback pointer and redirecting execution to attacker-chosen code (code execution) under the default configuration. Commit 540332be3e0acc566fa64da6f1b4680c72c724dd patches the issue. |
| IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to execute arbitrary commands due to improper validation of the ODMDIR environment variable. |
