CVE-2026-46218 | BDVDB-2026-336336 Detail
LinuxLinux
Description#
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Add bounds checking to ib_{get,set}_value The uvd/vce/vcn code accesses the IB at predefined offsets without checking that the IB is large enough. Check the bounds here. The caller is responsible for making sure it can handle arbitrary return values. Also make the idx a uint32_t to prevent overflows causing the condition to fail.
Impact#
Per CVSS v3.1: confidentiality impact high, integrity impact none, availability impact high. Attack vector: local.
Weaknesses#
No weakness recorded in the source data.
