CVE-2026-64156

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netfs, afs: Fix write skipping in dir/link writepages<br /> <br /> Fix netfs_write_single() and afs_single_writepages() to better handle a<br /> write that would be skipped due to lock contention and WB_SYNC_NONE by<br /> returning 1 from netfs_write_single() if it skipped and making<br /> afs_single_writepages() skip also. If a skip occurs, the inode must be<br /> re-marked as the VFS may have cleared the mark.<br /> <br /> This is really only theoretical for directories in netfs_write_single() as<br /> the only path to that is through afs_single_writepages() that takes the<br /> -&gt;validate_lock around it, thereby serialising it.
