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. l2capconfigreq in net/bluetooth/l2capcore.c has an integer wraparound via L2CAPCONF_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 slipclose() will act tocleanup necessary resources and sl->tty is set to NULL inslipclose(). Meanwhile, the packet we transmit is blocked,sltxtimeout() will be called. Although slipclose() andsltxtimeout() use sl->lock to synchronize, we don`t judgewhether sl-> tty equals to NULL in sltxtimeout() and thenull pointer dereference bug will happen.(Thread 1) | (Thread 2)| slipclose()| spinlockbh(& sl-> lock) sl-> tty = NULL //(1)sltxtimeout() | spinunlockbh(& sl->lock)spinlock(& sl-> lock);ttycharsinbuffer(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 cmdhdlfilter 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)
