CVE-2026-53293

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description Issues exist within the drm/amdgpu component specifically related to AMDGPU INFO READ MMR REG. The implementation contains several flaws: the sequence of the reset semaphore and the mm lock is incorrect, leading to copy to user() being executed while the lock is held. Additionally, memory is allocated while holding the reset semaphore, which can lead to a deadlock. The code also utilizes down read trylock() instead of waiting for the reset process to complete.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
