CVE-2026-49346

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in de265imagegetbuffer libde265/image.cc:128. The overflow wraps the plane allocation size to a sma...

EUVD-2026-36804

A signed integer overflow vulnerability was found in GStreamer's VMnc decoder. A crafted VMnc stream with large cursor dimensions can overflow signed integer payload-size arithmetic, bypassing a length check and leading to out-of-bounds reads. A remote attacker could trick a user into opening a...

CVE-2026-52722

GStreamer VMnc decoder in gstreamer1-plugins-bad-free contains a signed integer overflow in cursor payload handling. A crafted VMnc stream with large cursor dimensions can cause signed payload-size arithmetic overflow, bypass a length check, and lead to out-of-bounds reads. This may allow a remot...
