[ALAS2-2023-2027] Amazon Linux 2 2017.12 - ALAS2-2023-2027: important priority package update for kernel

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities:
CVE-2023-33203:
The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device.

CVE-2023-23454:
cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).

CVE-2023-2194:
An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace "data->block[0]" variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to crash the system or potentially achieve code execution.

CVE-2023-2124:
An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or potentially escalate their privileges on the system.

CVE-2023-2002:
An insufficient permission check has been found in the Bluetooth subsystem of
the Linux kernel when handling ioctl system calls of HCI sockets. This causes
tasks without the proper CAP_NET_ADMIN capability can easily mark HCI sockets
as trusted. Trusted sockets are intended to enable the sending and receiving
of management commands and events, such as pairing or connecting with a new
device. As a result, unprivileged users can acquire a trusted socket, leading
to unauthorized execution of management commands. The exploit requires only
the presence of a set of commonly used setuid programs (e.g., su, sudo).

CVE-2023-1838:
A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the system, and could even lead to a kernel information leak problem.
