CVE-2024-41059

Kernel-data disclosure via uninitialized HFS+ xattr buffer

Published Jul 29, 2024 · Updated Aug 5, 2026

Use of uninitialized memory in Linux kernel HFS+ xattr handling allows local users to read stale kernel data through listxattr. The hfsplus_listxattr function allocates strbuf without zeroing it, and copy_name passes uninitialized bytes to sized_strscpy while building the returned name list. Reaching the flaw requires a mounted HFS+ filesystem and local access to query extended-attribute names; the observed failure is an uninitialized-memory read.
