CWE-415  (opens in a new tab)

How to fix?

Upgrade RHEL:10 libarchive to version 0:3.7.7-10.el10_2 or higher.
This issue was patched in RHSA-2026:52675.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libarchive package and not the libarchive package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.
