CVE-2026-93813 btrfs: tree-checker: validate INODE_REF's namelen

In the Linux kernel, the following vulnerability has been resolved: btrfs: tree-checker: validate INODEREF's namelen BUG A crafted btrfs image can trigger the following crash: BUG: unable to handle page fault for address: ffffd1dc42884000 PF: supervisor write access in kernel mode PF:...

CVE-2026-93813

The Linux kernel contains a vulnerability in the btrfs file system where a crafted image with a corrupted INODE_REF item can trigger an out-of-boundary access. This occurs because the namelen can exceed the BTRFS_NAME_LEN limit of 255, while the allocated memory for @name remains only 255 bytes. ...
