In the Linux kernel, the following vulnerability has been resolved: xfs: stop reclaim before pushing AIL during unmount The unmount sequence in xfsunmountflushinodes pushed the AIL while background reclaim and inodegc are still running. This is broken independently of any use-after-free issues -...
CVE-2026-31455
A flaw was found in the Linux kernel's XFS file system. During the unmount process, the system attempts to flush data while background cleanup and inode garbage collection inodegc operations are still active. This improper synchronization can lead to data integrity issues or system instability, a...
CVE-2026-31446
A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability, a use-after-free, occurs due to a timing issue when the updatesuperwork function attempts to access memory that has already been released during a filesystem unmount operation. A local attacker could potentially exploit...
