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)

The following non-security bugs were fixed:

9p: virtio: make sure 'offs' is initialized in zc_request (git-fixes).
