Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.16.0-rc3-g90548c634bd0

Description A flaw exists in the Linux kernel's dm-bufio subsystem related to scheduling within atomic context. When try verify in tasklet is enabled for dm-verity and DM BUFIO CLIENT NO SLEEP is enabled for dm-bufio, attempting to evict buffers can trigger scheduling within a spin lock, leading to a kernel BUG. This can occur when using veritysetup to format devices and mounting them read-only.

Recommendations Linux kernel versions prior to 6.16.0-rc3-g90548c634bd0 should be updated.
