Descriptions
A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c.
Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue.
We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97.
Se encontró una vulnerabilidad de use-after-free en el subsistema netfilter del kernel de Linux en net/netfilter/nf_tables_api.c. El manejo de errores mal manejado con NFT_MSG_NEWRULE permite usar un puntero colgante en la misma transacción que causa una vulnerabilidad de use-after-free. Esta falla permite que un atacante local con acceso de usuario cause un problema de escalada de privilegios. Recomendamos actualizar al commit anterior 1240eb93f0616b21c675416516ff3d74798fdc97.
A use-after-free flaw was found in the Netfilter subsystem of the Linux kernel when processing named and anonymous sets in batch requests, which can lead to performing arbitrary reads and writes in kernel memory. This flaw allows a local user with CAP_NET_ADMIN capability to crash or potentially escalate their privileges on the system.
