CVE-2026-64156

In the Linux kernel, the following vulnerability has been resolved: netfs, afs: Fix write skipping in dir/link writepages Fix netfswritesingle and afssinglewritepages to better handle a write that would be skipped due to lock contention and WBSYNCNONE by returning 1 from netfswritesingle if it...

CVE-2026-64156

The CVE-2026-64156 vulnerability affects the Linux kernel’s netfs and AFS components. It arises when a write is skipped due to lock contention and WB_SYNC_NONE, potentially failing to re-mark the inode. The documented fix modifies netfs_write_single() to return 1 when a skip occurs and updates af...
