NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.
