kernel: netfilter: nf_tables: don't skip expired elements during walk

A flaw was found in the Linux kernel. Improper management of the lifecycle of some nftables objects could result in consumption of all system memory. An attacker who can create nftables rules could use this to effect a Denial of Service...

kernel: null pointer dereference vulnerability in nft_dynset_init()

A null pointer dereference vulnerability was found in nftdynsetinit in net/netfilter/nftdynset.c in nftables in the Linux kernel. This issue may allow a local attacker with CAPNETADMIN user privilege to trigger a denial of service...

kernel: nf_tables: use-after-free vulnerability in the nft_setelem_catchall_deactivate() function

A double-free flaw was found in how the Linux kernel's NetFilter system marks whether a catch-all element is enabled. A local user could use this flaw to crash the system...

kernel: netfilter: nf_tables: memory leak when more than 255 elements expired

A use-after-free flaw was found in the Linux kernel’s nftables sub-component due to a race problem between the set GC and transaction in the Linux Kernel. This flaw allows a local attacker to crash the system. This flaw is similar to the previous CVE-2023-4244 but for a different part of the sour...
