CVE-2026-46218

The vulnerability CVE-2026-46218 affects the Linux kernel DRM AMDGPU driver. The issue is in ib_get_value/ib_set_value where the uvd/vce/vcn code accessed the Instruction Buffer (IB) at predefined offsets without verifying the IB size, enabling out-of-bounds reads/writes. The root cause is missin...
