Red Hat Enterprise Linux 10: out-of-bounds read
Medium4.2CVE-2026-12548 · Published Jul 21, 2026 · updated Aug 24, 2026
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.
