A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem. This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)

A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle return with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

An out-of-bounds (OOB) memory access flaw was found in nft_fwd_dup_netdev_offload in net/netfilter/nf_dup_netdev.c in the netfilter subcomponent in the Linux kernel due to a heap out-of-bounds write problem. This flaw allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a privilege escalation threat. (CVE-2022-25636)
