Doc Text:
A flaw was found in the Linux kernel, specifically within the drm/amdgpu/vce component responsible for video encoding. This vulnerability arises when the system attempts to update a memory address using incomplete information, where only a portion of the address is valid. This can result in data being written to an unintended memory location in the firmware, which could allow an attacker to execute unauthorized code or disrupt system operations.
