CVE-2026-53129

In the Linux kernel, the following vulnerability has been resolved: fs/mbcache: cancel shrink work before destroying the cache mbcachedestroy calls shrinkerfree and then frees all cache entries and the cache itself, but it does not cancel the pending cshrinkwork work item first. If...

CVE-2026-53129

CVE-2026-53129 affects the Linux kernel mbcache shrink path. The bug occurs when mb_cache_destroy() frees memory without canceling the pending c_shrink_work, allowing mb_cache_shrink_worker() to access freed memory if mb_cache_entry_create() scheduled work via schedule_work() and the work item is...
