CVE-2026-89820

CVE-2026-89820 affects the Linux kernel 's drm/amd/display subsystem. On GPU reset, dm_suspend() acquires the dc_lock and defers its release to dm_resume(). If amdgpu_dm_commit_zero_streams() or dm_dmub_hw_init() fails, the error path returns without releasing the lock , causing every subsequent ...

CVE-2026-89811 drm/amdkfd: Add TLB flush after MES queue eviction/suspension

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Add TLB flush after MES queue eviction/suspension MES Micro Engine Scheduler does not perform heavy-weight TLB invalidation after unmapping queues, unlike HWS which does this automatically. This causes a race conditio...

CVE-2026-89811

CVE-2026-89811 affects the Linux kernel in the drm/amdkfd subsystem (AMD KFD driver). The MES (Micro Engine Scheduler) fails to perform a heavy-weight TLB invalidation after unmapping GPU queues—unlike HWS, which does so automatically. This creates a race condition where in-flight DMA descriptors...

Linux Kernel Security Vulnerabilities

Versions of the Linux kernel prior to 6.18.51 and 7.2.5 have security vulnerabilities. These vulnerabilities stem from the failure of TLB refresh after the MES queue is evicted or suspended, leading to race conditions. This can cause ongoing DMA descriptors to access memory that has been unmapped...
