| CVE-2025-15645 | 1 Ledger | 3 Flex, Nano X, Stax | 2026-05-20 | 4.6 Medium |
| Ledger Nano X, Flex, and Stax devices contain a denial of service vulnerability in the MCU firmware update process due to missing validation of the reset_handler parameter during firmware flashing. An attacker can provide a crafted reset_handler address pointing to invalid memory or attacker-controlled code to cause the device to enter an unrecoverable fault state during boot, resulting in permanent loss of operability. | ||||
| CVE-2026-32741 | 1 Struktur | 1 Libheif | 2026-05-20 | 7.1 High |
| libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and below contain a heap buffer overflow in MaskImageCodec::decode_mask_image(). When decoding a HEIF file containing a mask image (mski), the function copies the full iloc extent data into a pixel buffer using memcpy(dst, data.data(), data.size()). The copy length data.size() is determined by the iloc extent in the file (attacker-controlled), while the destination buffer is sized based on the declared image dimensions. Because no upper-bound check exists on the data length, a crafted file whose iloc extent exceeds the pixel buffer allocation overflows the heap. The vulnerable single-memcpy branch is reached when the mskC property specifies bits_per_pixel = 8 and the ispe property declares an even width ≥ 64 (so that stride == width), with no changes to default security limits or external codec plugins required. This issue has been fixed in version 1.22.0. | ||||
| CVE-2026-8956 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-05-20 | 9.8 Critical |
| Integer overflow in the Networking: JAR component. This vulnerability was fixed in Firefox 151, Firefox ESR 140.11, Thunderbird 151, and Thunderbird 140.11. | ||||
| CVE-2026-8959 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-05-20 | 9.6 Critical |
| Sandbox escape due to incorrect boundary conditions in the Widget: Win32 component. This vulnerability was fixed in Firefox 151, Firefox ESR 140.11, Thunderbird 151, and Thunderbird 140.11. | ||||
| CVE-2026-32738 | 1 Struktur | 1 Libheif | 2026-05-20 | 6.5 Medium |
| libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 792-byte HEIF sequence file with samples_per_chunk=0 in the stsc box causes an unsigned integer underflow in the Chunk constructor (m_last_sample = 0 + 0 - 1 = UINT32_MAX), mapping all samples to an empty chunk and resulting in a denial of service. When any sample is accessed, the library reads from index 0 of an empty std::vector, causing a guaranteed SEGV (null-page read). The file parses successfully without producing an error; the crash occurs on the first frame access. This issue has been fixed in version 1.22.0. | ||||
| CVE-2026-6843 | 2 Gnu, Redhat | 5 Nano, Enterprise Linux, Nano and 2 more | 2026-05-20 | 5.5 Medium |
| A flaw was found in nano. A local user could exploit a format string vulnerability in the `statusline()` function. By creating a directory with a name containing `printf` specifiers, the application attempts to display this name, leading to a segmentation fault (SEGV). This results in a Denial of Service (DoS) for the `nano` application. | ||||
| CVE-2024-36343 | 1 Amd | 17 Epyc 4004, Epyc 4005, Ryzen 6000 Series Processors With Radeon Graphics and 14 more | 2026-05-20 | N/A |
| Improper input validation in the System Management Mode (SMM) communications buffer could allow a privileged attacker to perform an out of bounds read or write to a limited section of the Top of Memory Segment (TSEG) memory region, potentially resulting in loss of confidentiality or integrity. | ||||
| CVE-2026-6846 | 3 Gnu, Iputils, Redhat | 7 Binutils, Iputils, Enterprise Linux and 4 more | 2026-05-20 | 7.8 High |
| A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable. | ||||
| CVE-2026-31401 | 1 Linux | 1 Linux Kernel | 2026-05-20 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: HID: bpf: prevent buffer overflow in hid_hw_request right now the returned value is considered to be always valid. However, when playing with HID-BPF, the return value can be arbitrary big, because it's the return value of dispatch_hid_bpf_raw_requests(), which calls the struct_ops and we have no guarantees that the value makes sense. | ||||
| CVE-2026-31405 | 1 Linux | 1 Linux Kernel | 2026-05-20 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: media: dvb-net: fix OOB access in ULE extension header tables The ule_mandatory_ext_handlers[] and ule_optional_ext_handlers[] tables in handle_one_ule_extension() are declared with 255 elements (valid indices 0-254), but the index htype is derived from network-controlled data as (ule_sndu_type & 0x00FF), giving a range of 0-255. When htype equals 255, an out-of-bounds read occurs on the function pointer table, and the OOB value may be called as a function pointer. Add a bounds check on htype against the array size before either table is accessed. Out-of-range values now cause the SNDU to be discarded. | ||||
| CVE-2026-7668 | 1 Mikrotik | 1 Routeros | 2026-05-20 | 7.3 High |
| A vulnerability was identified in MikroTik RouterOS 6.49.8. This vulnerability affects the function ASN1_STRING_data in the library nova/lib/www/scep.p of the component SCEP Endpoint. The manipulation of the argument transactionID/messageType leads to out-of-bounds read. The attack may be initiated remotely. The exploit is publicly available and might be used. You should upgrade the affected component. The vendor recommends to "use the latest v6.x or 7.x MikroTik RouterOS version, the reported issue should be fixed there." | ||||
| CVE-2026-45038 | 2 Eugeny, Tabby | 2 Tabby, Tabby | 2026-05-20 | 7.8 High |
| Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.233, since Tabby does not escape control characters from file paths when dragging and dropping a file into it, code execution can be achieved. This vulnerability is fixed in 1.0.233. | ||||
| CVE-2026-23956 | 1 Lxsmnsyc | 1 Seroval | 2026-05-20 | 7.5 High |
| seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. In versions 0.2.0 through 1.4.0, overriding RegExp serialization with extremely large patterns can exhaust JavaScript runtime memory during deserialization. Additionally, overriding RegExp serialization with patterns that trigger catastrophic backtracking can lead to ReDoS (Regular Expression Denial of Service). This issue has been fixed in version 1.4.1. | ||||
| CVE-2026-40175 | 1 Axios | 1 Axios | 2026-05-20 | 4.8 Medium |
| Axios is a promise based HTTP client for the browser and Node.js. Versions prior to 1.15.0 and 0.3.1 are vulnerable to a specific gadget-style attack chain in which prototype pollution in a third-party dependency may be leveraged to inject unsanitized header values into outbound requests. This vulnerability is fixed in 1.15.0 and 0.3.1. | ||||
| CVE-2026-31435 | 1 Linux | 1 Linux Kernel | 2026-05-19 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: netfs: Fix read abandonment during retry Under certain circumstances, all the remaining subrequests from a read request will get abandoned during retry. The abandonment process expects the 'subreq' variable to be set to the place to start abandonment from, but it doesn't always have a useful value (it will be uninitialised on the first pass through the loop and it may point to a deleted subrequest on later passes). Fix the first jump to "abandon:" to set subreq to the start of the first subrequest expected to need retry (which, in this abandonment case, turned out unexpectedly to no longer have NEED_RETRY set). Also clear the subreq pointer after discarding superfluous retryable subrequests to cause an oops if we do try to access it. | ||||
| CVE-2026-0438 | 2026-05-19 | N/A | ||
| A System Management Mode (SMM) handler could perform a callout to code located in non-SMM/untrusted memory. A highly privileged attacker could, with active user interaction and under high complexity and present preconditions, trigger execution of attacker-controlled code in SMM, potentially compromising the system’s confidentiality, integrity, and availability. | ||||
| CVE-2026-44288 | 2 Protobuf, Protobufjs Project | 2 Protobuf, Protobufjs | 2026-05-19 | 5.3 Medium |
| protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs includes a minimal UTF-8 decoder that accepted overlong UTF-8 byte sequences and decoded them to their canonical characters instead of replacing them. An attacker who can provide protobuf binary data decoded through the affected UTF-8 path may be able to bypass application-level checks that inspect raw bytes before protobuf string decoding. For example, bytes that do not contain certain ASCII characters could decode to strings containing those characters. This vulnerability is fixed in 7.5.6 and 8.0.2. | ||||
| CVE-2026-43092 | 1 Linux | 1 Linux Kernel | 2026-05-19 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: xsk: validate MTU against usable frame size on bind AF_XDP bind currently accepts zero-copy pool configurations without verifying that the device MTU fits into the usable frame space provided by the UMEM chunk. This becomes a problem since we started to respect tailroom which is subtracted from chunk_size (among with headroom). 2k chunk size might not provide enough space for standard 1500 MTU, so let us catch such settings at bind time. Furthermore, validate whether underlying HW will be able to satisfy configured MTU wrt XSK's frame size multiplied by supported Rx buffer chain length (that is exposed via net_device::xdp_zc_max_segs). | ||||
| CVE-2026-44246 | 2 Dkfz, Mic-dkfz | 2 Nnu-net, Nnunet | 2026-05-19 | 7.2 High |
| nnU-Net is a semantic segmentation framework that automatically adapts its pipeline to a dataset. Prior to 2.4.1, the nnU-Net Issue Triage workflow in .github/workflows/issue-triage.yml is vulnerable to Agentic Workflow Injection. The workflow sets allowed_non_write_users: ${{ github.event.issue.user.login }}, which means any logged-in GitHub user who opens an issue can reach this agentic workflow with attacker-controlled content. Untrusted issue title and body content are embedded directly into the prompt of anthropics/claude-code-action, and the workflow then runs a command-capable Claude agent with permission to comment on and relabel the current issue via gh. Because this workflow is triggered automatically on issues.opened, an external attacker can submit a crafted issue that steers the agent beyond its intended issue-triage purpose and influences authenticated issue actions. This vulnerability is fixed in 2.4.1. | ||||
| CVE-2026-8212 | 1 Osgeo | 1 Gdal | 2026-05-19 | 5.3 Medium |
| A flaw has been found in OSGeo gdal up to 3.13.0dev-4. Affected by this vulnerability is the function SWSDfldsrch of the file frmts/hdf4/hdf-eos/SWapi.c. Executing a manipulation can lead to heap-based buffer overflow. The attack requires local access. The exploit has been published and may be used. Upgrading to version 3.13.0RC1 addresses this issue. This patch is called 3e04c0385630e4d42517046d9a4967dfccfeb7fd. The affected component should be upgraded. | ||||
