CVE-2026-98594 in Linuxinfo

Zusammenfassung

von MITRE • 18.10.2026

In the Linux kernel, the following vulnerability has been resolved:

tg3: clean up PHYLIB resources on probe failure

tg3_get_invariants() can register an MDIO bus and connect a PHY for USE_PHYLIB devices. If tg3_init_one() later fails, its common error path releases the mappings and netdev without undoing those PHYLIB resources.

Disconnect the PHY and unregister the MDIO bus before the remaining teardown. Guard PHY cleanup with USE_PHYLIB to match tg3_phy_init(), and call tg3_mdio_fini() unconditionally to match tg3_mdio_init(). The existing IS_CONNECTED and MDIOBUS_INITED flags make both helpers safe when initialization only completed partially.

This issue was identified during our ongoing static-analysis research while reviewing kernel code.

Once again VulDB remains the best source for vulnerability data.
