CVE-2026-49346: CWE-190: Integer Overflow or Wraparound in strukturag libde265CVE-2026-49346 0 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 `de265_image_get_buffer()` (`libde265/image.cc:128`). The overflow wraps the plane allocation size to a small value (~1 KB), but the subsequent `fill_image()` call computes the real size using `size_t`, writing ~4 GB into the undersized heap buffer. Version 1.1.0 patches the issue. Join the discussion | CVE Database V5 | 06/19/2026, 20:12:14 UTC Added: 06/19/2026, 20:28:05 UTC |
