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.","state":0,"publishedAt":"2025-10-07T15:19:38.989+00:00","modifiedAt":"2026-10-15T21:41:32.53+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/ethernet/marvell/octeon_ep/octep_main.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"24d4333233b378114106a1327d3d635a004f4387\",\n                            \"lessThan\": \"62312e2f6466b5f0a120542a38b410d88a34ed00\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"24d4333233b378114106a1327d3d635a004f4387\",\n                            \"lessThan\": \"758c91078165ae641b698750a72eafe7968b3756\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/ethernet/marvell/octeon_ep/octep_main.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.4\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.4.12\",\n                            \"lessThanOrEqual\": \"6.4.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.5\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/62312e2f6466b5f0a120542a38b410d88a34ed00","https://git.kernel.org/stable/c/758c91078165ae641b698750a72eafe7968b3756"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-53638","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-53638","identifiers":["CVE-2023-53638"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
