CVE-2022-48807

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ice: Fix KASAN error in LAG NETDEV_UNREGISTER handler<br /> <br /> Currently, the same handler is called for both a NETDEV_BONDING_INFO<br /> LAG unlink notification as for a NETDEV_UNREGISTER call. This is<br /> causing a problem though, since the netdev_notifier_info passed has<br /> a different structure depending on which event is passed. The problem<br /> manifests as a call trace from a BUG: KASAN stack-out-of-bounds error.<br /> <br /> Fix this by creating a handler specific to NETDEV_UNREGISTER that only<br /> is passed valid elements in the netdev_notifier_info struct for the<br /> NETDEV_UNREGISTER event.<br /> <br /> Also included is the removal of an unbalanced dev_put on the peer_netdev<br /> and related braces.
