CVE-2022-50212

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: do not allow CHAINID to refer to another table When doing lookups for chains on the same batch by using its ID, a chain from a different table can be used. If a rule is added to a table but refers to a chain ...

CVE-2022-50213

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: do not allow SETID to refer to another table When doing lookups for sets on the same batch by using its ID, a set from a different table can be used. Then, when the table is removed, a reference to the set ma...

CVE-2022-50048

The CVE-2022-50048 vulnerability concerns the Linux kernel netfilter nf_tables component. The issue is a module reference underflow in the error path when nft_expr_clone() fails: dst->ops is set, but the module refcount hasn’t been bumped yet, so nft_expr_destroy() can underflow. Affected area...

Linux kernel competitive conditions vulnerability (CNVD-2025-10175)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel suffers from a competitive condition vulnerability that stems from nftables not releasing stream rule objects in a timely manner, which could lead to a memory leak...
