Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

There is an infoleak vulnerability in the Linux kernel's net/bluetooth/l2capcore.c's l2capparseconfreq function which can be used to leak kernel pointers remotely. We recommend upgrading past commit https://github.com/torvalds/linux/commit/b1a2cd50c0357f243b7435a732b4e62ba3157a2e https://www.google.com/url(CVE-2022-42895)

There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2capcore.c's l2capconnect and l2capleconnect_req functions which may allow code execution and leaking kernel memory (respectively) remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via Bluetooth if within proximity of the victim. We recommend upgrading past commit https://www.google.com/url https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4 https://www.google.com/url(CVE-2022-42896)
