When parsing a specially crafted H.265 bitstream containing a Screen Content Coding (SCC) extension with certain palette predictor initializer settings, an integer underflow in the upper-bound computation allows the parser to accept an out-of-range value for the number of palette predictor entries. This causes the parser to write beyond the end of a fixed-size array, resulting in memory corruption and an application crash. An attacker can deliver the malformed bitstream as a local file or over a network stream such as HTTP, HLS, DASH, RTSP, RTP, or WebRTC. Successful exploitation requires the application to open or play that content, and is limited to a denial-of-service impact.","severity":{"version":"3.1","score":6.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-12","score":0.00252,"percentile":0.16827,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-122"],"published":"2026-10-30T18:51:08Z","modified":"2026-11-04T09:47:23Z","fixes":[{"ecosystem":"Debian:14","package":"gst-plugins-bad1.0","fixed_in":["1.28.1-1"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Debian:12","package":"gst-plugins-bad1.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22.0-4","1.22.0-4+deb12u1","1.22.0-4+deb12u2","1.22.0-4+deb12u3","1.22.0-4+deb12u4","1.22.0-4+deb12u5","1.22.0-4+deb12u6","1.22.0-4+deb12u7","1.22.0-4+deb12u8","1.22.1-1","1.22.10-1","1.22.3-1","1.22.3-2","1.22.4-1","1.22.7-1","1.22.8-1","1.22.9-1","1.22.9-2","1.23.1-1","1.23.2-1","1.23.90-1","1.24.0-1","1.24.1-1","1.24.1-2","1.24.1-3","1.24.1-4","1.24.10-1","1.24.10-2","1.24.10-2+hurd.1","1.24.10-3","1.24.11-1","1.24.11-2","1.24.11-3","1.24.12-1","1.24.12-2","1.24.12-3","1.24.2-1","1.24.2-2","1.24.2-3","1.24.2-4","1.24.3-1","1.24.4-1","1.24.4-2","1.24.5-1","1.24.6-1","1.24.7-1","1.24.8-1","1.24.8-2","1.24.9-1","1.25.1-1","1.25.1-2","1.25.1-3","1.25.50-1","1.25.90-1","1.25.90-2","1.25.90-3","1.26.0-1","1.26.1-1","1.26.10-1","1.26.10-2","1.26.2-1","1.26.2-2","1.26.2-3","1.26.3-1","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.6-3","1.26.6-4","1.26.6-5","1.26.7-1","1.26.7-2","1.26.8-1","1.26.9-1","1.27.1-1","1.27.2-1","1.27.50-1","1.27.90-1","1.27.90-2","1.27.90-3","1.28.0-1","1.28.1-1","1.28.1-2","1.28.1-3","1.28.2-1","1.28.2-2","1.28.3-1","1.28.4-1","1.28.5-1","1.28.5-2","1.28.6-1","1.28.7-1","1.28.7-2","1.28.8-1","1.29.1-1","1.29.2-1","1.29.2-2"]},{"source":"osv","ecosystem":"Debian:13","package":"gst-plugins-bad1.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.26.10-1","1.26.10-2","1.26.2-3","1.26.2-3+deb13u1","1.26.2-3+deb13u2","1.26.2-3+deb13u3","1.26.3-1","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.6-3","1.26.6-4","1.26.6-5","1.26.7-1","1.26.7-2","1.26.8-1","1.26.9-1","1.27.1-1","1.27.2-1","1.27.50-1","1.27.90-1","1.27.90-2","1.27.90-3","1.28.0-1","1.28.1-1","1.28.1-2","1.28.1-3","1.28.2-1","1.28.2-2","1.28.3-1","1.28.4-1","1.28.5-1","1.28.5-2","1.28.6-1","1.28.7-1","1.28.7-2","1.28.8-1","1.29.1-1","1.29.2-1","1.29.2-2"]},{"source":"osv","ecosystem":"Debian:14","package":"gst-plugins-bad1.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.28.1-1"}]}],"versions":["1.26.10-1","1.26.10-2","1.26.2-3","1.26.3-1","1.26.4-1","1.26.5-1","1.26.5-2","1.26.6-1","1.26.6-2","1.26.6-3","1.26.6-4","1.26.6-5","1.26.7-1","1.26.7-2","1.26.8-1","1.26.9-1","1.27.1-1","1.27.2-1","1.27.50-1","1.27.90-1","1.27.90-2","1.27.90-3","1.28.0-1"]},{"source":"osv","ecosystem":"Ubuntu:Pro:14.04:LTS","package":"gst-plugins-bad1.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.0-3ubuntu5","1.2.1-1ubuntu1","1.2.1-1ubuntu2","1.2.2-1ubuntu1","1.2.2-1ubuntu2","1.2.2-1ubuntu4","1.2.3-1ubuntu1","1.2.3-1ubuntu2","1.2.4-1~ubuntu1","1.2.4-1~ubuntu1.1","1.2.4-1~ubuntu1.1+esm1"]},{"source":"osv","ecosystem":"Ubuntu:Pro:16.04:LTS","package":"gst-plugins-bad1.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0-1ubuntu1","1.6.1-1ubuntu1","1.6.2-1ubuntu1","1.7.1-1ubuntu1","1.7.1-1ubuntu3","1.7.1-1ubuntu4","1.7.2-1ubuntu1","1.7.90-1ubuntu2","1.7.91-1ubuntu1","1.8.0-1ubuntu1","1.8.1-1ubuntu0.1","1.8.2-1ubuntu0.1","1.8.2-1ubuntu0.2","1.8.3-1ubuntu0.2","1.8.3-1ubuntu0.2+esm1","1.8.3-1ubuntu0.2+esm2"]},{"source":"osv","ecosystem":"Ubuntu:Pro:18.04:LTS","package":"gst-plugins-bad1.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.3-1ubuntu1","1.12.3-1ubuntu2","1.12.3-2ubuntu1","1.12.4-2ubuntu1","1.12.4-2ubuntu2","1.13.1-1ubuntu1","1.13.91-1ubuntu1","1.14.0-1ubuntu1","1.14.1-1ubuntu1~ubuntu18.04.1","1.14.4-1ubuntu1~ubuntu18.04.1","1.14.5-0ubuntu1~18.04.1","1.14.5-0ubuntu1~18.04.1+esm1","1.14.5-0ubuntu1~18.04.1+esm2"]},{"source":"osv","ecosystem":"Ubuntu:Pro:20.04:LTS","package":"gst-plugins-bad1.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.16.1-1ubuntu1","1.16.1-1ubuntu3","1.16.1-1ubuntu4","1.16.1-1ubuntu5","1.16.1-1ubuntu6","1.16.1-1ubuntu8","1.16.2-1ubuntu1","1.16.2-1ubuntu2","1.16.2-2ubuntu1","1.16.2-2.1ubuntu1","1.16.3-0ubuntu1","1.16.3-0ubuntu1.1","1.16.3-0ubuntu1.1+esm1","1.16.3-0ubuntu1.1+esm2"]},{"source":"osv","ecosystem":"Ubuntu:Pro:22.04:LTS","package":"gst-plugins-bad1.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.18.5-1ubuntu1","1.18.5-1ubuntu3","1.20.0-2ubuntu2","1.20.1-1ubuntu2","1.20.3-0ubuntu1","1.20.3-0ubuntu1.1","1.20.3-0ubuntu1.1+esm2","1.20.3-0ubuntu1.1+esm3"]},{"source":"osv","ecosystem":"Ubuntu:Pro:24.04:LTS",
