CVE-2026-68309

The vulnerability CVE-2026-68309 affects the Linux kernel driver for wifi mt76 (Connac) and fixes a NULL-pointer dereference in mt76_connac_mcu_uni_bss_he_tlv(). The root cause is that mt76_connac_get_he_phy_cap could return NULL, and the code may dereference the cap pointer without checking. A p...

EUVD-2026-55307

In the Linux kernel, the following vulnerability has been resolved: media: v4l2-ctrls: validate HEVC active reference counts HEVC slice parameters are shared stateless V4L2 controls, but the common validation path does not verify the active L0/L1 reference counts before driver-specific code...

CVE-2026-64831

FFmpeg versions 8.0 through 8.1.2 contains a stack buffer overflow vulnerability in the Vulkan HEVC hardware decoder that allows remote attackers to overwrite return addresses and adjacent stack frames by supplying a crafted HEVC/H.265 bitstream. Attackers can embed a malicious vpsnumhrdparameter...

CVE-2026-47178 libheif has Heap Out Of Bounds Write in unci subsystem

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.19.0 through 1.21.2, a crafted HEIF file uncompressed unci codec, tiled, component-interleaved, 4:2:0 triggers a heap out-of-bounds write in libheif's uncompressed tile decoder. The write overwrites the C++ vtable pointer o...

The vulnerability of the h.265 Libde265 implementation lies in the execution of operations beyond the buffer boundaries in memory, which allows an attacker to cause a service failure.

The vulnerability of the h.265 Libde265 implementation is related to the execution of operations outside the buffer in memory when processing the variable ctbinfo.log2unitSize. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-53257

A flaw was found in the Linux kernel. An issue within the mac80211 Wi-Fi subsystem, specifically related to the enforcement of High Efficiency HE and Extremely High Throughput EHT capabilities and operations, could lead to a system crash. This vulnerability arises when HE/EHT capabilities are set...

CVE-2026-53257

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: enforce HE/EHT cap/oper consistency Xiang Mei reports that mac80211 could crash if ehtcap is set but ehtoper isn't. Rather than fixing that for the individual users, enforce that both HE/EHT have consistent elemen...

CVE-2026-53257 wifi: cfg80211: enforce HE/EHT cap/oper consistency

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: enforce HE/EHT cap/oper consistency Xiang Mei reports that mac80211 could crash if ehtcap is set but ehtoper isn't.

CVE-2026-53257

The CVE-2026-53257 entry concerns the Linux kernel wifi subsystem (cfg80211/mac80211). The issue arises when HE (High Efficiency) and EHT elements are inconsistent between capabilities and operations, which could trigger a crash if eht_cap is set but eht_oper isn’t. The vulnerability is addressed...

PT-2026-52352

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A crash can occur in the mac80211 component of the wifi cfg80211 module when eht cap is set but eht oper is not. To prevent this, the system must enforce consistency between High...

EUVD-2026-38606

A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266...

UBUNTU-CVE-2026-49295

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted H.265 bitstream can cause an out-of-bounds array write in decodercontext::processreferencepictureset libde265/decctx.cc:1376. The root cause is a missing aggregate bound check on predicted...

CVE-2026-49346

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in de265imagegetbuffer libde265/image.cc:128. The overflow wraps the plane allocation size to a sma...

USN-8438-1: OpenImageIO vulnerabilities
