CVE-2026-89827

This Linux kernel vulnerability affects the drm/amdgpu driver's UVD (Unified Video Decoder) handling in SR-IOV VF contexts. The root cause is that uvd_v7_0_sw_init() does not initialize the UVD decode ring for a virtual function, yet amdgpu_uvd_resume() unconditionally force-completes that decode...

CVE-2026-89818

CVE-2026-89818 is an integer overflow in the Linux kernel's drm/amdgpu/vcn driver, specifically in the dec_msg buffer count check. If the supplied msg[2] (num_buffers) is 0x3FFFFFFF, the expression 6 + num_buffers * 4 wraps to 2, causing the bounds check to pass and allowing the parser loop to re...
