If no MACs were\nregistered, NAPI was never enabled. Also, if they were registered but\nsubsequently unregistered, NAPI was already disabled in\nmal_unregister_commac(). In either case, calling napi_disable() causes\nthe kernel to hang upon module removal.\n\nFix this by only calling napi_disable() in mal_remove() if the commac list\nis not empty (which implies NAPI is enabled)."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/ibm/emac/mal.c"],"versions":[{"version":"b3e441c6ed8655a42e7b4da1b6dc7939f259d9c9","lessThan":"9c1c814a662d9c81959eba591bb52b24639390f2","status":"affected","versionType":"git"},{"version":"b3e441c6ed8655a42e7b4da1b6dc7939f259d9c9","lessThan":"34c4cae51718d6f393415e01c61314c1bde02f2e","status":"affected","versionType":"git"},{"version":"b3e441c6ed8655a42e7b4da1b6dc7939f259d9c9","lessThan":"62126e73e230cf4bd6c27cf201949c4290af84a1","status":"affected","versionType":"git"},{"version":"b3e441c6ed8655a42e7b4da1b6dc7939f259d9c9","lessThan":"f0399b3e212741bc5a64b8399d6266c4a150bdfe","status":"affected","versionType":"git"},{"version":"b3e441c6ed8655a42e7b4da1b6dc7939f259d9c9","lessThan":"f6c1aad9b35fa083f48ce0c5926204891d82e089","status":"affected","versionType":"git"},{"version":"b3e441c6ed8655a42e7b4da1b6dc7939f259d9c9","lessThan":"c4cb9a728df66c46067b26263f5beb633aae4087","status":"affected","versionType":"git"},{"version":"b3e441c6ed8655a42e7b4da1b6dc7939f259d9c9","lessThan":"7c5d41f87f079990bf241359e3c1332d8d10fe87","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/ibm/emac/mal.c"],"versions":[{"version":"2.6.24","status":"affected"},{"version":"0","lessThan":"2.6.24","status":"unaffected","versionType":"semver"},{"version":"5.10.271","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.222","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"2.6.24","versionEndExcluding":"5.10.271"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.24","versionEndExcluding":"5.15.222"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.24","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.24","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.24","versionEndExcluding":"6.12.111"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.24","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.24","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9c1c814a662d9c81959eba591bb52b24639390f2"},{"url":"https://git.kernel.org/stable/c/34c4cae51718d6f393415e01c61314c1bde02f2e"},{"url":"https://git.kernel.org/stable/c/62126e73e230cf4bd6c27cf201949c4290af84a1"},{"url":"https://git.kernel.org/stable/c/f0399b3e212741bc5a64b8399d6266c4a150bdfe"},{"url":"https://git.kernel.org/stable/c/f6c1aad9b35fa083f48ce0c5926204891d82e089"},{"url":"https://git.kernel.org/stable/c/c4cb9a728df66c46067b26263f5beb633aae4087"},{"url":"https://git.kernel.org/stable/c/7c5d41f87f079990bf241359e3c1332d8d10fe87"}],"title":"net: ibm: emac: mal: fix potential system hang in mal_remove()","x_generator":{"engine":"bippy-1.2.0"}}}}
