Answer in brief
CVE-2022-50048 records a High severity (CVSS 7.8) vulnerability in netfilter: nf_tables: possible module reference underflow in error path. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: possible module reference underflow in error path dst->ops is set on when nft_expr_clone() fails, but module refcount has not been bumped yet, therefore nft_expr_destroy() leads to module reference underflow.
