If tg3_init_one() later fails, its common error path\nreleases the mappings and netdev without undoing those PHYLIB resources.\n\nDisconnect the PHY and unregister the MDIO bus before the remaining\nteardown. Guard PHY cleanup with USE_PHYLIB to match tg3_phy_init(), and\ncall tg3_mdio_fini() unconditionally to match tg3_mdio_init(). The existing\nIS_CONNECTED and MDIOBUS_INITED flags make both helpers safe when\ninitialization only completed partially.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/broadcom/tg3.c"],"versions":[{"version":"158d7abdae85e9ac43d99780c372d79c119f7626","lessThan":"ce86d6929d03e6b0abcb781dfa50f9f0816bff78","status":"affected","versionType":"git"},{"version":"158d7abdae85e9ac43d99780c372d79c119f7626","lessThan":"a449eedb3b1eb5b8b1f5ed116a1bfe85eaaf81df","status":"affected","versionType":"git"},{"version":"158d7abdae85e9ac43d99780c372d79c119f7626","lessThan":"0844402326d4e48a28688f93ec6442e93bb442fa","status":"affected","versionType":"git"},{"version":"158d7abdae85e9ac43d99780c372d79c119f7626","lessThan":"e766321288b507afb70d2bfef6ba443213329f79","status":"affected","versionType":"git"},{"version":"158d7abdae85e9ac43d99780c372d79c119f7626","lessThan":"d2abb0013b933d59ee441185df0eca9e8c0b33eb","status":"affected","versionType":"git"},{"version":"158d7abdae85e9ac43d99780c372d79c119f7626","lessThan":"6515c41503eef849abd2c7364f34e4bb25110f90","status":"affected","versionType":"git"},{"version":"158d7abdae85e9ac43d99780c372d79c119f7626","lessThan":"b6c0c757c65893ad7bb17e8bcf33cdd8257d7b3d","status":"affected","versionType":"git"},{"version":"158d7abdae85e9ac43d99780c372d79c119f7626","lessThan":"a92e1a412c53dc0d9ad639e7abf8b3fc70a5b6ad","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/broadcom/tg3.c"],"versions":[{"version":"2.6.27","status":"affected"},{"version":"0","lessThan":"2.6.27","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":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.55","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.9","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","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":"2.6.27","versionEndExcluding":"5.10.271"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.27","versionEndExcluding":"5.15.222"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.27","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.27","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.27","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.27","versionEndExcluding":"6.18.55"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.27","versionEndExcluding":"7.2.9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.27","versionEndExcluding":"7.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ce86d6929d03e6b0abcb781dfa50f9f0816bff78"},{"url":"https://git.kernel.org/stable/c/a449eedb3b1eb5b8b1f5ed116a1bfe85eaaf81df"},{"url":"https://git.kernel.org/stable/c/0844402326d4e48a28688f93ec6442e93bb442fa"},{"url":"https://git.kernel.org/stable/c/e766321288b507afb70d2bfef6ba443213329f79"},{"url":"https://git.kernel.org/stable/c/d2abb0013b933d59ee441185df0eca9e8c0b33eb"},{"url":"https://git.kernel.org/stable/c/6515c41503eef849abd2c7364f34e4bb25110f90"},{"url":"https://git.kernel.org/stable/c/b6c0c757c65893ad7bb17e8bcf33cdd8257d7b3d"},{"url":"https://git.kernel.org/stable/c/a92e1a412c53dc0d9ad639e7abf8b3fc70a5b6ad"}],"title":"tg3: clean up PHYLIB resources on probe failure","x_generator":{"engine":"bippy-1.2.0"}}}}
