  script_tag(name:"insight", value:"This kernel-linus update is based on upstream 5.15.110 and fixes at least
the following security issues:

A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in
drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c.
This issue could occur when assoc_info->req_len data is bigger than the
size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of
service (CVE-2023-1380).

It was discovered that a race condition existed in the Xen transport layer
implementation for the 9P file system protocol in the Linux kernel, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service or expose sensitive information (CVE-2023-1859).

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 (CVE-2023-2002).

A heap out-of-bounds read/write vulnerability in the Linux Kernel traffic
control (QoS) subsystem can be exploited to achieve local privilege
escalation. The qfq_change_class function does not properly limit the lmax
variable which can lead to out-of-bounds read/write. If the TCA_QFQ_LMAX
value is not offered through nlattr, lmax is determined by the MTU value
of the network device. The MTU of the loopback device can be set up to
2^31-1 and as a result, it is possible to have an lmax value that exceeds
QFQ_MIN_LMAX (CVE-2023-2248).

qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13
allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX
(CVE-2023-31436).

For other upstream fixes in this update, see the referenced changelogs.");
