CVE-2022-48813

CVE-2022-48813 concerns the Linux kernel’s DSA Felix support. The advisory notes that using devres for the MDIO bus caused mdiobus_free() to panic when freed via devm_mdiobus_free(), unless the bus was unregistered first. For the Felix VSC9959 switch (PCI device), the recommended remediation is t...

CVE-2022-48812

CVE-2022-48812 concerns the Linux kernel: the net: dsa: lantiq_gswip code should not use devres for mdiobus allocation/registration. The root cause is that mdiobus_free() can panic when invoked via devm_mdiobus_free() because devres_release_all() may free a bus that is still registered, especiall...
