## Description:

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed:

  * CVE-2020-26555: Fixed Bluetooth legacy BR/EDR PIN code pairing in Bluetooth
    Core Specification 1.0B that may permit an unauthenticated nearby device to
    spoof the BD_ADDR of the peer device to complete pairing without knowledge
    of the PIN (bsc#1179610 bsc#1215237).
  * CVE-2022-45887: Fixed a memory leak in ttusb_dec.c caused by the lack of a
    dvb_frontend_detach call (bsc#1205762).
  * CVE-2023-1206: Fixed a hash collision flaw in the IPv6 connection lookup
    table which could be exploited by network adjacent attackers, increasing CPU
    usage by 95% (bsc#1212703).
  * CVE-2023-31085: Fixed a divide-by-zero error in do_div(sz,mtd->erasesize)
    that could cause a local DoS (bsc#1210778).
  * CVE-2023-3111: Fixed a use-after-free vulnerability in prepare_to_relocate
    in fs/btrfs/relocation.c (bsc#1212051).
  * CVE-2023-39189: Fixed a flaw in the Netfilter subsystem that could allow a
    local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read,
    leading to a crash or information disclosure (bsc#1216046).
  * CVE-2023-39192: Fixed an out of bounds read in the netfilter (bsc#1215858).
  * CVE-2023-39193: Fixed an out of bounds read in the xtables subsystem
    (bsc#1215860).
  * CVE-2023-39197: Fixed a out-of-bounds read in nf_conntrack_dccp_packet()
    (bsc#1216976).
  * CVE-2023-45863: Fixed a out-of-bounds write in fill_kobj_path()
    (bsc#1216058).
  * CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race
    condition in bt_sock_recvmsg (bsc#1218559).
  * CVE-2023-6606: Fixed an out of bounds read in the SMB client when receiving
    a malformed length from a server (bsc#1217947).
  * CVE-2023-6932: Fixed a use-after-free vulnerability in the Linux kernel's
    ipv4: igmp component that could lead to local privilege escalation
    (bsc#1218253).
