{"id":"CVE-2024-42107","summary":"ice: Don't process extts if PTP is disabled","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nice: Don't process extts if PTP is disabled\n\nThe ice_ptp_extts_event() function can race with ice_ptp_release() and\nresult in a NULL pointer dereference which leads to a kernel panic.\n\nPanic occurs because the ice_ptp_extts_event() function calls\nptp_clock_event() with a NULL pointer. The ice driver has already\nreleased the PTP clock by the time the interrupt for the next external\ntimestamp event occurs.\n\nTo fix this, modify the ice_ptp_extts_event() function to check the\nPTP state and bail early if PTP is not ready.","modified":"2026-04-02T12:17:47.220342Z","published":"2024-07-30T07:46:02.834Z","related":["SUSE-SU-2024:3190-1","SUSE-SU-2024:3194-1","SUSE-SU-2024:3195-1","SUSE-SU-2024:3209-1","SUSE-SU-2024:3383-1","SUSE-SU-2024:3483-1","SUSE-SU-2025:20044-1","SUSE-SU-2025:20047-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/42xxx/CVE-2024-42107.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1c4e524811918600683b1ea87a5e0fc2db64fa9b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/996422e3230e41468f652d754fefd1bdbcd4604e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/42xxx/CVE-2024-42107.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-42107"},{"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":"172db5f91d5f7b91670c68a7547798b0b5374158"},{"fixed":"1c4e524811918600683b1ea87a5e0fc2db64fa9b"},{"fixed":"996422e3230e41468f652d754fefd1bdbcd4604e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-42107.json"}}],"schema_version":"1.7.5"}
