CVE-2026-68300

Summary: CVE-2026-68300 in the Linux kernel concerns SCTP authentication. The function sctp_auth_chunk_verify() incorrectly returns true when auth_chunk is NULL, allowing authentication to be bypassed under certain conditions (e.g., skb_clone() failure in BH path or absence of an AUTH before COOK...

CVE-2026-68278

The CVE-2026-68278 entry documents a Linux kernel vulnerability in drm/dp/mst sideband processing (drm_dp_sideband_append_payload). Three bugs allow out-of-bounds writes when processing device-provided sideband replies: (1) zero-length curchunk_len underflow leading to 255-byte reads/writes beyon...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate CPGFXSHADOW chunk size in CS pass1 Add a minimum-length check for the AMDGPUCHUNKIDCPGFXSHADOW chunk in amdgpucspass1, matching the gate already present for the IB, FENCE and BOHANDLES chunk types. The...

CVE-2026-68272

The CVE-2026-68272 affects the Linux kernel DRM/AMDGPU stack. It introduces a minimum-length validation for the AMDGPU_CHUNK_ID_CP_GFX_SHADOW chunk in amdgpu_cs_pass1(), so undersized chunks (length_dw == 0) are now rejected with -EINVAL before pass2 dereferences data. Previously, a zero-size poi...

FFmpeg through 8.1.2, fixed in commit b506faf, contains a heap out-of-bounds write vulnerability in the native PNG and APNG encoders that allows remote attackers to corrupt heap memory by supplying a crafted PNG image with a malicious eXIf chunk. Attackers can craft an eXIf chunk where multiple I...
