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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/marvell/octeon_ep/octep_main.c"],"versions":[{"version":"24d4333233b378114106a1327d3d635a004f4387","lessThan":"62312e2f6466b5f0a120542a38b410d88a34ed00","status":"affected","versionType":"git"},{"version":"24d4333233b378114106a1327d3d635a004f4387","lessThan":"758c91078165ae641b698750a72eafe7968b3756","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/marvell/octeon_ep/octep_main.c"],"versions":[{"version":"6.4","status":"affected"},{"version":"0","lessThan":"6.4","status":"unaffected","versionType":"semver"},{"version":"6.4.12","lessThanOrEqual":"6.4.*","status":"unaffected","versionType":"semver"},{"version":"6.5","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.4.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.5"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/62312e2f6466b5f0a120542a38b410d88a34ed00"},{"url":"https://git.kernel.org/stable/c/758c91078165ae641b698750a72eafe7968b3756"}],"title":"octeon_ep: cancel queued works in probe error path","x_generator":{"engine":"bippy-1.2.0"}}}}
