kernel: netfilter: nf_tables: disallow anonymous set with timeout flag

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: disallow anonymous set with timeout flag Anonymous sets are never used with timeout from userspace, reject this. Exception to this rule is NFTSETEVAL to ensure legacy meters still work...

kernel: netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout

A vulnerability was found in the netfilter/nftables subsystem of Linux Kernel, where a race condition caused where the garbage collector could prematurely collect elements from anonymous sets with timeouts while they were being released...

SUSE CVE-2021-47312

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: Fix dereference of null pointer flow In the case where chain-flags & NFTCHAINHWOFFLOAD is false then nftflowrulecreate is not called and flow is NULL. The subsequent error handling execution via label...

kernel: netfilter: nf_tables: disallow timeout for anonymous sets

A vulnerability was found in netfilter/nftables componets of Linux Kernel allows an userspace to set timeouts for anonymous sets, which are not intended to be used this way. This could lead to unexpected behaviour or security issues...

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...

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...
