{"id":"CVE-2026-97600","summary":"ieee802154: cc2520: fix FIFOP work use-after-free","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nieee802154: cc2520: fix FIFOP work use-after-free\n\nThe FIFOP interrupt handler queues cc2520_fifop_irqwork.  On removal,\ncc2520_remove() only flushes the work.  The devm-managed FIFOP IRQ\nremains active until after -\u003eremove() returns and can queue the work\nagain after that flush, allowing it to run after the private data is\nreleased.\n\nDisable the work with disable_work_sync() instead of flushing it, so\nthe handler can no longer queue it once removal begins.  Destroy the\nbuffer mutex last, since the worker and the stop callback invoked\nthrough ieee802154_unregister_hw() both take it.\n\nFound by an in-house static analysis tool.","modified":"2026-09-26T03:48:36.143453061Z","published":"2026-09-25T10:22:14.197Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97600.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/56a9919d8494fb118eebf167bef0622528fbf2e7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/890a80d516a1447db5c21bf92841a82914ea897d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c68fd52c73b676aee67020011e98fea125a978f4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ff5891b266a7fc6a062710836be84f1cc19338b5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97600.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97600"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0da6bc8cc3417a5e452efb886ff2c61e72b743d6"},{"fixed":"56a9919d8494fb118eebf167bef0622528fbf2e7"},{"fixed":"c68fd52c73b676aee67020011e98fea125a978f4"},{"fixed":"890a80d516a1447db5c21bf92841a82914ea897d"},{"fixed":"ff5891b266a7fc6a062710836be84f1cc19338b5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97600.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.17.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97600.json"}}],"schema_version":"1.9.0"}
