{"id":"CVE-2026-74451","summary":"drm/panthor: validate firmware interface structure sizes","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/panthor: validate firmware interface structure sizes\n\niface_fw_to_cpu_addr() only checks that the firmware-provided MCU virtual\naddress points inside the shared section. The returned pointer is later\nused as a full firmware interface structure, so accepting an address near\nthe end of the shared section can still lead to out-of-bounds accesses.\n\nPass the expected object size to iface_fw_to_cpu_addr() and reject ranges\nthat do not fit entirely in the shared section.","modified":"2026-08-18T03:56:49.014413304Z","published":"2026-08-15T12:26:55.722Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74451.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/21c77486f5a60bb9c0433c21de62a5f25d5091f1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b921b8613790a3f9e78ab64017fa7149ef0b750c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c835f2b0b7167584832b516c9b0a26e9180d1d0b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca41d9f3a21586bf29df53eec05152ecf2b2f94f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74451.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74451"},{"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":"21c77486f5a60bb9c0433c21de62a5f25d5091f1"},{"fixed":"c835f2b0b7167584832b516c9b0a26e9180d1d0b"},{"fixed":"ca41d9f3a21586bf29df53eec05152ecf2b2f94f"},{"fixed":"b921b8613790a3f9e78ab64017fa7149ef0b750c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74451.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.10.0"},{"fixed":"6.12.103"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.44"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74451.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
