UBUNTU-CVE-2024-36286

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkqueue: acquire rcureadlock in instancedestroyrcu syzbot reported that nfreinject could be called without rcureadlock : WARNING: suspicious RCU usage 6.9.0-rc7-syzkaller-02060-g5c1672705a1a 0 Not tainted...

CVE-2024-36286

CVE-2024-36286 is a Linux kernel issue where netfilter nfnetlink_queue could call nf_reinject() without holding rcu_read_lock, risking suspicious RCU usage. The resolution adds proper RCU handling in instance_destroy_rcu() and related paths (e.g., nf_reinject, nfqnl_flush) to ensure rcu_read_lock...
