An attacker could possibly use this issue to\ncause libde265 to crash, resulting in a denial of service. This issue\nonly affected Ubuntu 22.04 LTS. (CVE-2023-51792)\n\nIt was discovered that libde265 did not properly handle certain\nmalformed media files, leading to a heap buffer overflow. An attacker\ncould possibly use this issue to cause libde265 to crash, resulting in\na denial of service. (CVE-2024-38949, CVE-2024-38950)\n\nIt was discovered that libde265 did not properly handle certain\nmalformed input, leading to a segmentation fault. An attacker could\npossibly use this issue to cause libde265 to crash, resulting in a\ndenial of service. (CVE-2025-61147)\n\nIt was discovered that libde265 did not properly handle a malformed\nH.265 PPS NAL unit, leading to a segmentation fault. An attacker could\npossibly use this issue to cause libde265 to crash, resulting in a\ndenial of service. (CVE-2026-33164)\n\nIt was discovered that libde265 did not properly handle certain\ncrafted HEVC bitstreams, leading to an out-of-bounds write. An attacker\ncould possibly use this issue to cause libde265 to crash, resulting in\na denial of service. (CVE-2026-33165)\n\nValentin Mercier discovered that libde265 did not properly validate\ntile geometry when handling crafted media files, leading to an\nout-of-bounds read. An attacker could possibly use this issue to cause\nlibde265 to crash, resulting in a denial of service, or to obtain\nsensitive information. (CVE-2026-45382)\n\nIt was discovered that libde265 did not properly validate certain\nvalues when decoding crafted media files, leading to an out-of-bounds\nread. An attacker could possibly use this issue to cause libde265 to\ncrash, resulting in a denial of service, or to obtain sensitive\ninformation. (CVE-2026-45383)\n\nYing Dong discovered that libde265 did not properly validate reference\npicture set entries when handling a crafted H.265 bitstream, leading to\nan out-of-bounds write. An attacker could possibly use this issue to\ncause libde265 to crash, resulting in a denial of service, or possibly\nexecute arbitrary code. (CVE-2026-49295)\n\nYing Dong discovered that libde265 did not properly manage memory when\nhandling a crafted sequence of H.265 NAL units, leading to excessive\nmemory consumption. An attacker could possibly use this issue to cause\nlibde265 to use excessive resources, leading to a denial of service.\n(CVE-2026-49337)\n\nYing Dong discovered that libde265 did not properly handle certain\ncrafted H.265 bitstreams with large dimensions, leading to a heap\nbuffer overflow. An attacker could possibly use this issue to cause\nlibde265 to crash, resulting in a denial of service, or possibly\nexecute arbitrary code. (CVE-2026-49346)\n\nIt was discovered that libde265 did not properly handle certain crafted\nHEVC bitstreams with large dimensions, leading to an out-of-bounds\nread and write. An attacker could possibly use this issue to cause\nlibde265 to crash, resulting in a denial of service, or possibly\nexecute arbitrary code. (CVE-2026-54240)\n\nIt was discovered that libde265 did not properly handle certain crafted\nHEVC bitstreams with large dimensions, leading to a heap buffer\noverflow. An attacker could possibly use this issue to cause libde265\nto crash, resulting in a denial of service, or possibly execute\narbitrary code.
