- 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-2023-2163: Fixed an incorrect verifier pruning in BPF that could lead to unsafe code paths being incorrectly marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and container escape. (bsc#1215518)
- CVE-2023-3777: Fixed a use-after-free vulnerability in netfilter: nf_tables component can be exploited to achieve local privilege escalation. (bsc#1215095)
- 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-2023-3111: Fixed a use-after-free vulnerability in prepare_to_relocate in fs/btrfs/relocation.c (bsc#1212051).
- 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).
The following non-security bugs were fixed:
- bpf: propagate precision in ALU/ALU64 operations (git-fixes).
- KVM: x86: fix sending PV IPI (git-fixes, bsc#1210853, bsc#1216134).
- nvme-fc: Prevent null pointer dereference in nvme_fc_io_getuuid() (bsc#1214842).
