There is no fixed version for RHEL:10 libsoup3-doc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup3-doc package and not the libsoup3-doc package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A heap out-of-bounds read flaw was found in libsoup. When parsing multipart HTTP messages, an integer type mismatch between the caller and soup_headers_parse() can cause the length parameter to be incorrectly truncated, leading to a heap buffer over-read. A remote attacker could use this flaw to crash an application using libsoup or potentially disclose heap memory contents.
