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

A flaw was found in the Netfilter subsystem in the Linux kernel. This issue occurs in the nftverdictinit function, allowing positive values as a drop error within the hook verdict, therefore, the nfhookslow function can cause a double-free vulnerability when NFDROP is issued with a drop error tha...

kernel: netfilter: nf_tables: possible module reference underflow in error path

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: possible module reference underflow in error path dst-ops is set on when nftexprclone fails, but module refcount has not been bumped yet, therefore nftexprdestroy leads to module reference underflow...

kernel: Linux kernel: Denial of Service in netfilter due to improper garbage collection

A flaw was found in the Linux kernel's netfilter component, specifically within the nftsetrbtree module. A local user with low privileges could exploit an issue where the garbage collection mechanism fails to properly release memory during interval expiration walks. This can lead to a memory leak...

The vulnerability of the netfilter component in the Linux operating system’s kernel, located in the nft_verdict_init() function, allows an attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the netfilter component in the Linux operating system’s kernel is related to the use of memory after it is freed in the function nftverdictinit within the net/netfilter/nftablesapi.c module. Exploiting this vulnerability can allow an attacker to compromise the confidentiality...
