5.5 · MEDIUM
Published Jul 10, 2025 linux CWE-476 EPSS 0.16% (6th pctl)

Overview

CVE-2025-38337 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 10, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

jbd2: fix data-race and null-ptr-deref in jbd2_journal_dirty_metadata()

Since handle->h_transaction may be a NULL pointer, so we should change it

to call is_handle_aborted(handle) first before dereferencing it.

And the following data-race was reported in my fuzzer:
