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...

CVE-2026-49346

CVE-2026-49346 affects libde265 up to version 1.0.x; a crafted H.265 bitstream with large SPS dimensions and 16-bit depth triggers a signed integer overflow in de265_image_get_buffer(), causing an undersized allocation (~1 KB) but later writing ~4 GB due to size_t math in fill_image. This is fixe...

CVE-2026-49295

CVE-2026-49295 affects libde265. Before version 1.0.20, crafted H.265 bitstreams can trigger an out-of-bounds write in decoder_context::process_reference_picture_set() due to a missing aggregate bound check on predicted short-term reference picture set entries; while individual list sizes are che...

CVE-2026-49295 libde265 has an out-of-bounds write in process_reference_picture_set via predicted short-term RPS

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted H.265 bitstream can cause an out-of-bounds array write in decodercontext::processreferencepictureset libde265/decctx.cc:1376. The root cause is a missing aggregate bound check on predicted...

CVE-2026-49337

CVE-2026-49337 affects libde265 prior to 1.0.20. A crafted sequence of H.265 NAL units lets decoder_context::read_slice_NAL() attach slice headers to a finished picture object with no active image unit, causing attacker-controlled unbounded heap growth. The headers are retained until the picture ...
