  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
