{"id":"CVE-2026-98594","summary":"tg3: clean up PHYLIB resources on probe failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ntg3: clean up PHYLIB resources on probe failure\n\ntg3_get_invariants() can register an MDIO bus and connect a PHY for\nUSE_PHYLIB devices. 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.","modified":"2026-10-20T02:30:20.470230153Z","published":"2026-10-18T15:19:06.696Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98594.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0844402326d4e48a28688f93ec6442e93bb442fa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6515c41503eef849abd2c7364f34e4bb25110f90"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a449eedb3b1eb5b8b1f5ed116a1bfe85eaaf81df"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a92e1a412c53dc0d9ad639e7abf8b3fc70a5b6ad"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b6c0c757c65893ad7bb17e8bcf33cdd8257d7b3d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce86d6929d03e6b0abcb781dfa50f9f0816bff78"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d2abb0013b933d59ee441185df0eca9e8c0b33eb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e766321288b507afb70d2bfef6ba443213329f79"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98594.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98594"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"158d7abdae85e9ac43d99780c372d79c119f7626"},{"fixed":"ce86d6929d03e6b0abcb781dfa50f9f0816bff78"},{"fixed":"a449eedb3b1eb5b8b1f5ed116a1bfe85eaaf81df"},{"fixed":"0844402326d4e48a28688f93ec6442e93bb442fa"},{"fixed":"e766321288b507afb70d2bfef6ba443213329f79"},{"fixed":"d2abb0013b933d59ee441185df0eca9e8c0b33eb"},{"fixed":"6515c41503eef849abd2c7364f34e4bb25110f90"},{"fixed":"b6c0c757c65893ad7bb17e8bcf33cdd8257d7b3d"},{"fixed":"a92e1a412c53dc0d9ad639e7abf8b3fc70a5b6ad"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98594.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.27"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98594.json"}}],"schema_version":"1.9.0"}
