Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

An issue was discovered in the Linux kernel through 6.0.10. l2cap_config_req in net/bluetooth/l2cap_core.c has an integer wraparound via L2CAP_CONF_REQ packets.(CVE-2022-45934)

There are null-ptr-deref vulnerabilities in drivers/net/slip of linux that allow attacker tocrash linux kernel by simulating slip network card from user-space of linux.[Root cause]When a slip driver is detaching, the slip_close() will act tocleanup necessary resources and sl->tty is set to NULL inslip_close(). Meanwhile, the packet we transmit is blocked,sl_tx_timeout() will be called. Although slip_close() andsl_tx_timeout() use sl->lock to synchronize, we don`t judgewhether sl-> tty equals to NULL in sl_tx_timeout() and thenull pointer dereference bug will happen.(Thread 1) | (Thread 2)| slip_close()| spin_lock_bh(& sl-> lock) sl-> tty = NULL //(1)sl_tx_timeout() | spin_unlock_bh(& sl->lock)spin_lock(& sl-> lock);tty_chars_in_buffer(sl-> tty)|if (tty-> ops-> ..) //(2)synchronize_rcu()We set NULL to sl-> tty in position (1) and dereference sl-> ttyin position (2).(CVE-2022-41858)

A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and gain escalation of privileges.(CVE-2022-4095)
