CVE-2026-98310 is a known-severity vulnerability. It was published on October 6, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/shrinker: Take a runtime PM ref before shrinking non-system memory
__xe_shrinker_walk() walks the SYSTEM and TT LRUs without a runtime PM
reference. Shrinking a bo outside system memory invalidates its GPU
mappings, which needs the device resumed, so while it is runtime
suspended the page table zap trips an assert and the TLB invalidation
returns -ENODEV:
WARNING: drivers/gpu/drm/xe/xe_bo.c:770 at xe_bo_move_notify+0x1fc/0x450 [xe]

Take a reference before walking a memory type other than XE_PL_SYSTEM
and stop there if it cannot be acquired. Reuse the shrinker's existing
acquire path, which resumes the device directly where reclaim allows
that and otherwise queues the PM worker for a later scan. Stop the walk
once the scan targe
