A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability.We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8. ipv4: fix null-deref in ipv4_link_failureNOTE: https://www.openwall.com/lists/oss-security/2023/10/02/8NOTE: https://git.kernel.org/linus/0113d9c9d1ccc07f5a3710dac4aa24b6d711278c A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSET_CMD_ADD and IPSET_CMD_SWAP can lead to a kernel panic due to the invocation of `__ip_set_put` on a wrong `set`. This issue may allow a local user to crash the system. A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free.We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325
