DEBIAN-CVE-2022-50048

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...

CVE-2022-50048

In Linux kernels affected by CVE-2022-50048, the vulnerability is in netfilter nf_tables: if nft_expr_clone() fails, dst->ops is set before the module refcount is bumped, causing an underflow in nft_expr_destroy(). This is a kernel-level issue that can affect systems using nf_tables, and is de...
