CVE-2026-72100

HIGH

8.8

CVSS v3

Description

In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix a bug if the bio is out of limits If dm_integrity_check_limits fails, the code would exit with DM_MAPIO_KILL. However, the range would be already locked at this point, and it wouldn't be unlocked, resulting in a deadlock. Let's move the limit check up, so that when it exits, no resources are leaked.
