CVE-2025-38328

5.5 · MEDIUM
Published Jul 10, 2025 linux CWE-476 EPSS 0.18% (8th pctl)

Overview

CVE-2025-38328 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:

jffs2: check jffs2_prealloc_raw_node_refs() result in few other places

Fuzzing hit another invalid pointer dereference due to the lack of

checking whether jffs2_prealloc_raw_node_refs() completed successfully.

Subsequent logic implies that the node refs have been allocated.

Handle that. The code is ready for propagating the error upwards.

KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f]
