{"id":"CVE-2026-80577","summary":"drm/panthor: skip zero-sized firmware sections","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/panthor: skip zero-sized firmware sections\n\npanthor_fw_load_section_entry() skips BO creation when the firmware section\nVA range is empty. If such a section is added to the firmware section list,\nsection-\u003emem is left as NULL.\n\nLater reload and unplug paths iterate over all firmware sections and\ndereference section-\u003emem, which can lead to a NULL pointer dereference.\n\nZero-sized firmware sections are valid, so accept them as no-op entries but\nskip adding them to the section list.","modified":"2026-08-28T11:48:23.513697141Z","published":"2026-08-26T14:37:36.132Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80577.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/25556a46ae6ecf2a9f1c1c5096828eecd4596b91"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2b8f13d3c7e26c46c20d9e367904cf01729c88e6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5d222b657f02a37f658e4e21925b85b4703855e7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f0f3c3922db981031733a25c51e1f37cf9b9e251"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80577.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80577"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2718d91816eeed03c09c8abe872e45f59078768c"},{"fixed":"f0f3c3922db981031733a25c51e1f37cf9b9e251"},{"fixed":"25556a46ae6ecf2a9f1c1c5096828eecd4596b91"},{"fixed":"5d222b657f02a37f658e4e21925b85b4703855e7"},{"fixed":"2b8f13d3c7e26c46c20d9e367904cf01729c88e6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80577.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.10.0"},{"fixed":"6.12.105"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.46"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80577.json"}}],"schema_version":"1.9.0"}
