{"id":"CVE-2025-71306","summary":"ima: Fix stack-out-of-bounds in is_bprm_creds_for_exec()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nima: Fix stack-out-of-bounds in is_bprm_creds_for_exec()\n\nKASAN reported a stack-out-of-bounds access in ima_appraise_measurement\nfrom is_bprm_creds_for_exec:\n\nBUG: KASAN: stack-out-of-bounds in ima_appraise_measurement+0x12dc/0x16a0\n Read of size 1 at addr ffffc9000160f940 by task sudo/550\nThe buggy address belongs to stack of task sudo/550\nand is located at offset 24 in frame:\n  ima_appraise_measurement+0x0/0x16a0\nThis frame has 2 objects:\n  [48, 56) 'file'\n  [80, 148) 'hash'\n\nThis is caused by using container_of on the *file pointer. This offset\ncalculation is what triggers the stack-out-of-bounds error.\n\nIn order to fix this, pass in a bprm_is_check boolean which can be set\ndepending on how process_measurement is called. If the caller has a\nlinux_binprm pointer and the function is BPRM_CHECK we can determine\nis_check and set it then. Otherwise set it to false.","modified":"2026-07-16T00:29:43.184920619Z","published":"2026-05-27T12:14:57.182Z","related":["CGA-7rxm-mj7f-gw33"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71306.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/377cae9851e8559e9d8b82a78c1ac0abeb18839c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab3d16da982a4ebb715d487dbf9dd66e3990d935"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71306.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71306"},{"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":"95b3cdafd7cb74414070893445a9b731793f7b55"},{"fixed":"ab3d16da982a4ebb715d487dbf9dd66e3990d935"},{"fixed":"377cae9851e8559e9d8b82a78c1ac0abeb18839c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71306.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.19.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71306.json"}}],"schema_version":"1.7.5"}
