Medium [CVE-2026-38347] Heap overflow vulnerability leads to Denial of Service
CVE-2026-38347Source published Source updated
A heap overflow in the ff_sws_alphablendaway function (libswscale/alphablend.c) of FFmpeg git-master commit 722a217 allows attackers to cause a Denial of Service (DoS) via a crafted input. A flaw was found in FFmpeg. Successful exploitation could lead to the application becoming unresponsive or crashing. The ffmpeg package is not shipped in base Red Hat Enterprise Linux. It is available through EPEL, Red Hat Enterprise Linux AI, and as a bundled dependency in Red Hat OpenShift AI container images. The vulnerable code resides in libswscale, which is compiled and shipped in all FFmpeg builds across these products. This is a heap overflow rather than a simple denial of service, which could potentially have higher impact if the overflow is controllable by an attacker. Red Hat severity…
