  - There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect
    and l2cap_le_connect_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)

  - drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-
    space client to corrupt the monitor's internal memory. (CVE-2022-43750)

  - A flaw incorrect access control in the Linux kernel USB core subsystem was found in the way user attaches
    usb device. A local user could use this flaw to crash the system. (CVE-2022-4662)

  - In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows
    an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control
    configuration that is set up with 'tc qdisc' and 'tc class' commands. This affects qdisc_graft in
    net/sched/sch_api.c. (CVE-2022-47929)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network
    subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - 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-2023-23454)

  - atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial
    of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition
    rather than valid classification results). (CVE-2023-23455)
