- Summary
- idpf: avoid vport access in idpf_get_link_ksettings
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
idpf: avoid vport access in idpfgetlink_ksettings
When the device control plane is removed or the platform running device control plane is rebooted, a reset is detected on the driver. On driver reset, it releases the resources and waits for the reset to complete. If the reset fails, it takes the error path and releases the vport lock. At this time if the monitoring tools tries to access link settings, it call traces for accessing released vport pointer.
To avoid it, move linkspeedmbps to netdevpriv structure which removes the dependency on vport pointer and the vport lock in idpfgetlinkksettings. Also use netifcarrierok() to check the link status and adjust the offsetof to use linkup instead of linkspeed_mbps.
