CVE-2026-49346 libde265 has a heap buffer overflow in de265_image_get_buffer via SPS dimension integer overflow

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...
