kernel: nf_tables: use-after-free in nft_chain_lookup_byid()

A use-after-free flaw was found in the Linux kernel's Netfilter module in net/netfilter/nftablesapi.c in nftchainlookupbyid. This flaw allows a local attacker to cause a local privilege escalation issue due to a missing cleanup...

Vulnerabilities of functions nftFlushTable(), nfTablesDelChain(), nfTablesNewRule(), nfTablesDelRule(), and __nftReleaseTable() in Linux kernel, which allow attackers to compromise the confidentiality, integrity, and accessibility of protected information, or enhance their privileges.

The vulnerabilities of the functions nftFlushTable, nfTablesDelChain, nfTablesNewRule, nfTablesDelRule, and nftReleaseTable in the Linux kernel are related to the reutilization of previously freed memory. Exploiting these vulnerabilities can allow an attacker to compromise the confidentiality,...

kernel: netfilter: use-after-free due to improper element removal in nft_pipapo_remove()
