This vulnerability arises because VRAM (Video Random Access Memory) allocations for the KFD (Kernel Fusion Driver) path do not properly clear previously used memory. This oversight allows a local attacker, utilizing a compute kernel, to observe stale data from prior VRAM usage, leading to information disclosure.
