{"id":"CVE-2023-53638","summary":"octeon_ep: cancel queued works in probe error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nocteon_ep: cancel queued works in probe error path\n\nIf it fails to get the devices's MAC address, octep_probe exits while\nleaving the delayed work intr_poll_task queued. When the work later\nruns, it's a use after free.\n\nMove the cancelation of intr_poll_task from octep_remove into\noctep_device_cleanup. This does not change anything in the octep_remove\nflow, but octep_device_cleanup is called also in the octep_probe error\npath, where the cancelation is needed.\n\nNote that the cancelation of ctrl_mbox_task has to follow\nintr_poll_task's, because the ctrl_mbox_task may be queued by\nintr_poll_task.","modified":"2026-04-02T09:44:39.366918Z","published":"2025-10-07T15:19:38.989Z","related":["SUSE-SU-2025:21040-1","SUSE-SU-2025:21052-1","SUSE-SU-2025:21056-1","SUSE-SU-2025:21064-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4128-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4140-1","SUSE-SU-2025:4141-1","SUSE-SU-2025:4301-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53638.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/62312e2f6466b5f0a120542a38b410d88a34ed00"},{"type":"WEB","url":"https://git.kernel.org/stable/c/758c91078165ae641b698750a72eafe7968b3756"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53638.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53638"},{"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":"24d4333233b378114106a1327d3d635a004f4387"},{"fixed":"62312e2f6466b5f0a120542a38b410d88a34ed00"},{"fixed":"758c91078165ae641b698750a72eafe7968b3756"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53638.json"}}],"schema_version":"1.7.5"}
