CVE-2022-49622 netfilter: nf_tables: avoid skb access on nf_stolen

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: avoid skb access on nfstolen When verdict is NFSTOLEN, the skb might have been freed. When tracing is enabled, this can result in a use-after-free: 1. access to skb-nftrace 2. access to skb-mark 3. computatio...

CVE-2022-49622

CVE-2022-49622 (Linux kernel) describes a use-after-free risk in nf_tables when verdict is NF_STOLEN in netfilter, where skb freeing may have occurred. The fix prevents illegal skb access by: (1) caching skb->nf_trace in the trace state and refreshing it when verdict != STOLEN; (2) skipping sk...

CVE-2022-49558

CVE-2022-49558 affects the Linux kernel nf_tables/netfilter path. The issue is a double unregistration of hooks in netns path: __nft_release_hooks() unregisters hooks during pre_netns exit, and NETDEV_UNREGISTER triggers unregister again, leading to potential hook handling inconsistencies. The pr...
