 - kernel: swiotlb information leak with DMA_FROM_DEVICE (CVE-2022-0854)

 - kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM (CVE-2022-1016)

 - kernel: race condition in snd_pcm_hw_free leading to use-after-free (CVE-2022-1048)

 - kernel: use-after-free and memory errors in ext4 when mounting and operating on a corrupted image (CVE-2022-1184)

 - kernel: NULL pointer dereference in x86_emulate_insn may lead to DoS (CVE-2022-1852)

 - kernel: net/packet: slab-out-of-bounds access in packet_recvmsg() (CVE-2022-20368)

 - hw: cpu: Intel: Post-barrier Return Stack Buffer Predictions (CVE-2022-26373)

 - kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-2022-2639)

 - kernel: memory leak in drivers/hid/hid-elo.c (CVE-2022-27950)

 - kernel: double free in ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c (CVE-2022-28390)

 - kernel: use after free in SUNRPC subsystem (CVE-2022-28893)

 - kernel: use-after-free when psi trigger is destroyed while being polled (CVE-2022-2938)

 - kernel: use-after-free due to improper update of reference count in net/sched/cls_u32.c (CVE-2022-29581)

 - kernel: DoS in nfqnl_mangle in net/netfilter/nfnetlink_queue.c (CVE-2022-36946)
