A use-after-free vulnerability in the Linux Kernel traffic control index
filter (tcindex) can be exploited to achieve local privilege escalation.
The tcindex_delete function which does not properly deactivate filters in
case of a perfect hashes while deleting the underlying structure which can
later lead to double freeing the structure. A local attacker user can use
this vulnerability to elevate its privileges to root. We recommend
upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28.
