## Description:

The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed:

  * CVE-2023-31085: Fixed a divide-by-zero error in do_div(sz,mtd->erasesize)
    that could cause a local DoS. (bsc#1210778)
  * CVE-2023-45862: Fixed an issue in the ENE UB6250 reader driver whwere an
    object could potentially extend beyond the end of an allocation causing.
    (bsc#1216051)
  * CVE-2023-34324: Fixed a possible deadlock in Linux kernel event handling.
    (bsc#1215745).
  * 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-2023-39194: Fixed an out of bounds read in the XFRM subsystem
    (bsc#1215861).
  * CVE-2023-39193: Fixed an out of bounds read in the xtables subsystem
    (bsc#1215860).
  * CVE-2023-39192: Fixed an out of bounds read in the netfilter (bsc#1215858).
  * CVE-2023-42754: Fixed a NULL pointer dereference in the IPv4 stack that
    could lead to denial of service (bsc#1215467).
  * 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-2023-4921: Fixed a use-after-free vulnerability in the QFQ network
    scheduler which could be exploited to achieve local privilege escalation
    (bsc#1215275).
  * CVE-2023-4622: Fixed a use-after-free vulnerability in the Unix domain
    sockets component which could be exploited to achieve local privilege
    escalation (bsc#1215117).
  * CVE-2023-4623: Fixed a use-after-free issue in the HFSC network scheduler
    which could be exploited to achieve local privilege escalation
    (bsc#1215115).
  * CVE-2020-36766: Fixed a potential information leak in in the CEC driver
    (bsc#1215299).
  * CVE-2023-1859: Fixed a use-after-free flaw in Xen transport for 9pfs which
    could be exploited to crash the system (bsc#1210169).
  * CVE-2023-4881: Fixed a out-of-bounds write flaw in the netfilter subsystem
    that could lead to potential information disclosure or a denial of service
    (bsc#1215221).
  * CVE-2023-40283: Fixed use-after-free in l2cap_sock_ready_cb (bsc#1214233).
  * CVE-2023-1192: Fixed use-after-free in cifs_demultiplex_thread()
    (bsc#1208995).

The following non-security bugs were fixed:

  * check-for-config-changes: ignore BUILTIN_RETURN_ADDRESS_STRIPS_PAC
    (bsc#1214380). gcc7 on SLE 15 does not support this while later gcc does.
  * mkspec: Allow unsupported KMPs (bsc#1214386)
  * old-flavors: Drop 2.6 kernels. 2.6 based kernels are EOL, upgrading from
    them is no longer suported.
