{"id":"CVE-2024-39292","summary":"um: Add winch to winch_handlers before registering winch IRQ","details":"In the Linux kernel, the following vulnerability has been resolved:\n\num: Add winch to winch_handlers before registering winch IRQ\n\nRegistering a winch IRQ is racy, an interrupt may occur before the winch is\nadded to the winch_handlers list.\n\nIf that happens, register_winch_irq() adds to that list a winch that is\nscheduled to be (or has already been) freed, causing a panic later in\nwinch_cleanup().\n\nAvoid the race by adding the winch to the winch_handlers list before\nregistering the IRQ, and rolling back if um_request_irq() fails.","modified":"2026-03-20T12:37:12.777672Z","published":"2024-06-24T13:52:26.769Z","related":["MGASA-2024-0263","MGASA-2024-0266"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/39xxx/CVE-2024-39292.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0c02d425a2fbe52643a5859a779db0329e7dddd4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/31960d991e43c8d6dc07245f19fc13398e90ead2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/351d1a64544944b44732f6a64ed65573b00b9e14"},{"type":"WEB","url":"https://git.kernel.org/stable/c/434a06c38ee1217a8baa0dd7c37cc85d50138fb0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/66ea9a7c6824821476914bed21a476cd20094f33"},{"type":"WEB","url":"https://git.kernel.org/stable/c/73b8e21f76c7dda4905655d2e2c17dc5a73b87f1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a0fbbd36c156b9f7b2276871d499c9943dfe5101"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc1ff95602ee908fcd7d8acee7a0dadb61b1a0c0"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/39xxx/CVE-2024-39292.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-39292"},{"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":"42a359e31a0e438b5b978a8f0fecdbd3c86bb033"},{"fixed":"66ea9a7c6824821476914bed21a476cd20094f33"},{"fixed":"dc1ff95602ee908fcd7d8acee7a0dadb61b1a0c0"},{"fixed":"351d1a64544944b44732f6a64ed65573b00b9e14"},{"fixed":"31960d991e43c8d6dc07245f19fc13398e90ead2"},{"fixed":"0c02d425a2fbe52643a5859a779db0329e7dddd4"},{"fixed":"434a06c38ee1217a8baa0dd7c37cc85d50138fb0"},{"fixed":"73b8e21f76c7dda4905655d2e2c17dc5a73b87f1"},{"fixed":"a0fbbd36c156b9f7b2276871d499c9943dfe5101"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-39292.json"}}],"schema_version":"1.7.5"}
