CVE-2026-23036

In the Linux kernel, the following vulnerability has been resolved: btrfs: release path before igetfailed in btrfsreadlockedinode In btrfsreadlockedinode if we fail to lookup the inode, we jump to the 'out' label with a path that has a read locked leaf and then we call igetfailed. This can result...

CVE-2026-23036

The CVE-2026-23036 entry describes a Linux kernel vulnerability in the Btrfs path: release path before iget_failed() in btrfs_read_locked_inode().
