CVE-2022-42720

kernel: use-after-free in bss_ref_get in net/wireless/scan.c

Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-free conditions to potentially execute code.

CVE-2022-2586

kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation

It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted.

CVE-2022-41218

kernel: Report vmalloc UAF in dvb-core/dmxdev

In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release.

CVE-2022-39188

kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings leads to stale TLB entry

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.

CVE-2022-36946

kernel: DoS in nfqnl_mangle in net/netfilter/nfnetlink_queue.c

nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.

CVE-2022-32250

kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root

net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free.

CVE-2022-4269

kernel: net: CPU soft lockup in TC mirred egress-to-ingress action

A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.
