{"id":"AZL-42937","summary":"CVE-2024-39292 affecting package kernel for versions less than 5.15.162.2-1","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":"2026-04-01T05:14:55.742395Z","published":"2024-06-24T14:15:12Z","upstream":["CVE-2024-39292"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-39292"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.162.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-42937.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
