CVE-2022-48817

CVE-2022-48817 is a Linux kernel issue affecting the ar9331 MDIO switch under the DSA subsystem. The root cause is that mdiobus registration was done under devres and could be freed by devm_mdiobus_free() via device core shutdown, leading to a panic if the bus was still registered. The advisory e...

CVE-2022-48814

CVE-2022-48814 affects the Linux kernel DSA seville driver (VSC9959) where mdiobus was allocated/registered with devres. The root cause is a devres interaction causing mdiobus to be freed without prior unregistration, leading to mdiobus_free() panics when invoked from devm_mdiobus_free(). The pro...
