Overview

CVE-2025-38382 is a high-severity vulnerability. It was published on July 25, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix iteration of extrefs during log replay

At __inode_add_ref() when processing extrefs, if we jump into the next

label we have an undefined value of victim_name.len, since we haven't

initialized it before we did the goto. This results in an invalid memory

access in the next iteration of the loop since victim_name.len was not

initialized to the length of the name of the current extref.

Fix this by initializing victim_name.len with the current extref's name

length.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
