NVD Description

Note: Versions mentioned in the description apply only to the upstream bpftool package and not the bpftool package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nfnetlink_log: cope with concurrent instance destruction

Instances are refcounted. However, only memory release happens on the 1 -> 0 transition; the unlink from hashes can occur with any refcount.

Uncooperative userspace can force a situation where a queue is pending for destruction from netlink event while a different socket with same portid processes an UNBIND request.

With right timing, this will unhash the instance again:

Oops: general protection fault, [..] Call Trace: <TASK> nfulnl_recv_config+0x31a/0xd50 nfnetlink_rcv_msg+0x7c2/0xeb0
