In the Linux kernel, the following vulnerability has been resolved:
ipv6: add NULL checks for idev in SRv6 paths
_in6devget() can return NULL when the device has no IPv6 configuration (e.g. MTU < IPV6MINMTU or after NETDEVUNREGISTER).
Add NULL checks for idev returned by _in6devget() in both seg6hmacvalidateskb() and ipv6srhrcv() to prevent potential NULL pointer dereferences.
