CVE-2026-31566

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

Description A use-after-free issue exists in the amdgpu amdkfd submit ib() function. The function submits a GPU job and receives a fence from amdgpu ib schedule() to wait for job completion. The code incorrectly releases the fence reference using dma fence put() before calling dma fence wait(). If dma fence put() releases the final reference, the fence may be freed before the wait operation occurs, leading to the use of freed memory.

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