CWEhttps://cwe.mitre.org/data/definitions/415.html

A double free issue has been identified in libarchives 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.

Weakness

The product calls free() twice on the same memory address.
