CVE-2025-38496

A flaw was found in the Linux kernel's device mapper (dm-bufio) component. When the 'try_verify_in_tasklet' option is enabled for dm-verity, it can lead to scheduling in an atomic context while dm-bufio attempts to evict buffers. A local attacker with low privileges could exploit this by triggering specific dm-verity and dm-bufio configurations, causing a kernel panic and resulting in a Denial of Service (DoS).
