Judge has assessed an item in Issue 2142 as 2 risk. The relevant finding follows: LOW1: No whenNotPaused in redeem Technical Details Almost all state changing functions have whenNotPaused in the core contract but it is not the case for redeem. The NFT it interact with has a pause/unpause...

kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval()

An out-of-bounds OOB memory access flaw was found in the Netfilter module in the Linux kernel's nftbyteordereval in net/netfilter/nftbyteorder.c. A bound check failure allows a local attacker with CAPNETADMIN access to cause a local privilege escalation issue due to incorrect data alignment...

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()

A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nftpipaporemove function with the element, without a NFTSETEXTKEYEND. This issue could allow a local user to crash the system or potentially escalate their privileges on the system...
