{"id":"CVE-2026-68444","summary":"firmware: arm_ffa: Fix NULL dereference in ffa_partition_info_get()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: arm_ffa: Fix NULL dereference in ffa_partition_info_get()\n\nffa_partition_info_get() passes uuid_str directly to uuid_parse()\nwithout a NULL check. When a caller passes NULL, uuid_parse() -\u003e\n__uuid_parse() -\u003e uuid_is_valid() dereferences the pointer, causing\na kernel panic:\n\n  |  Unable to handle kernel NULL pointer dereference at virtual address\n  |  0000000000000040\n  |  pc : uuid_parse+0x40/0xac\n  |  lr : ffa_partition_info_get+0x1c/0x94 [arm_ffa]\n\nAdd a NULL guard before uuid_parse() so a NULL argument returns\n-ENODEV instead of crashing. Callers are expected to always supply\na valid partition UUID, so NULL is not a supported input.","modified":"2026-08-13T04:02:57.519266900Z","published":"2026-08-12T00:07:34.609Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68444.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/12a42c610e4432e7708cc48d607e5903fffe0aad"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7201e56e52d18abf4cd0a2fee45daf9dc08b5b97"},{"type":"WEB","url":"https://git.kernel.org/stable/c/86f5ea90f73bb7154593bb96f3411e197f3d4fbe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8ae5f8e4836667fcaffdf2e3c6068b0a8b364dd8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/996c5c19d5b5ac5b98a7b5a406b548305841c301"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68444.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68444"},{"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":"d0c0bce831223b08e5bade2cefc93c3ddb790796"},{"fixed":"86f5ea90f73bb7154593bb96f3411e197f3d4fbe"},{"fixed":"7201e56e52d18abf4cd0a2fee45daf9dc08b5b97"},{"fixed":"996c5c19d5b5ac5b98a7b5a406b548305841c301"},{"fixed":"12a42c610e4432e7708cc48d607e5903fffe0aad"},{"fixed":"8ae5f8e4836667fcaffdf2e3c6068b0a8b364dd8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68444.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.14.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68444.json"}}],"schema_version":"1.9.0"}
