What is CVE-2026-112214?
CVE-2026-112214 is a medium-severity denial of service vulnerability in Red Hat Enterprise Linux 10, published on 19 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
A flaw was found in the GStreamer ASF demuxer in gst-plugins-ugly. When parsing a Simple Index object, an attacker-controlled entry count is used to size a heap allocation without being limited to the payload available in the object. Processing a crafted ASF, WMV, or WMA file can cause a very large memory allocation request and lead to denial of service if the allocation fails or the process is memory-constrained.
Weakness: CWE-789
