Last modified
CVE-2025-21679 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: btrfs: add the missing error handling inside get_canonical_dev_path Inside function get_canonical_dev_path(), we call d_path() to get the final device path. But d_path() can return error, and in that case the next strscpy() call will trigger an invalid memory access. Add back the missing error handling for d_path().. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
