CVE-2023-53062

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

kcm: close race conditions on sk_receive_queue

sk->sk_receive_queue is protected by skb queue lock, but for KCM sockets its RX path takes mux->rx_lock to protect more than just skb queue. However, kcm_recvmsg() still only grabs the skb queue lock, so race conditions still exist.

We can teach kcm_recvmsg() to grab mux->rx_lock too but this would introduce a potential performance regression as struct kcm_mux can be shared by multiple KCM sockets.

So we have to enforce skb queue lock in requeue_rx_msgs() and handle skb peek case carefully in kcm_wait_data(). Fortunately, skb_recv_datagram() already handles it nicely and is widely used by other sockets, we can just switch to skb_recv_datagram() after getting rid of the unnecessary sock lock in kcm_recvmsg() and kcm_splice_read(). Side note: SOCK_DONE is not used by KCM sockets, so it is safe to get rid of this check too.

I ran the original syzbot reproducer for 30 min without seeing any issue.(CVE-2022-49814)

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

ipvs: fix WARNING in ip_vs_app_net_cleanup()

During the initialization of ip_vs_app_net_init(), if file ip_vs_app fails to be created, the initialization is successful by default. Therefore, the ip_vs_app file doesn't be found during the remove in ip_vs_app_net_cleanup(). It will cause WRNING.
