CVE-2023-53125

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.

In the Linux kernel, the following vulnerability has been resolved: net: usb: smsc75xx: Limit packet length to skb->len Packet length retrieved from skb data may be larger than the actual socket buffer length (up to 9026 bytes). In such case the cloned skb passed up the network stack will leak kernel memory contents.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

• kernel: net: usb: smsc75xx: Limit packet length to skb->len (CVE-2023-53125)
• kernel: net/sched: Always pass notifications when child class becomes empty (CVE-2025-38350)
• kernel: idpf: convert control queue mutex to a spinlock (CVE-2025-38392)
• kernel: drm/gem: Acquire references on GEM handles for framebuffers (CVE-2025-38449)

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

net: usb: smsc75xx: Limit packet length to skb->len

Packet length retrieved from skb data may be larger than the actual socket buffer length (up to 9026 bytes). In such case the cloned skb passed up the network stack will leak kernel memory contents.

The SUSE Linux Enterprise 15 SP4 RT kernel was updated to receive various security bugfixes.

The following security bugs were fixed:

• CVE-2022-49110: netfilter: conntrack: revisit gc autotuning (bsc#1237981).
• CVE-2022-49139: Bluetooth: fix null ptr deref on hci_sync_conn_complete_evt (bsc#1238032).
• CVE-2022-49767: 9p/trans_fd: always use O_NONBLOCK read/write (bsc#1242493).
• CVE-2022-49775: tcp: cdg: allow tcp_cdg_release() to be called multiple times (bsc#1242245).

• CVE-2025-37789: net: openvswitch: fix nested key length validation in the set() action (bsc#1242762).

The following non-security bugs were fixed:

• Drivers: hv: Allow vmbus_sendpacket_mpb_desc() to create multiple ranges (bsc#1243737).
• Refresh fixes for cBPF issue (bsc#1242778)
• Remove debug flavor (bsc#1243919)
