CVE-2026-89642

A flaw was found in the Linux kernel's Common Internet File System CIFS implementation. When a client extends a file, the cifssetsize function fails to properly zero out the newly extended portion of the page cache. This oversight can lead to stale data from the client's memory being written back...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from the fact that cifssetsize calls truncatepagecache during expansion, but skips pagecacheisizeextended. As a result, the tail of the page that spans across the old EOF page is not cleared, allowing dirty bytes to be writte...
