Answer in brief
CVE-2022-49997 records a High severity (CVSS 7.5) vulnerability in net: lantiq_xrx200: restore buffer if memory allocation failed. 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 7.5. 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: net: lantiq_xrx200: restore buffer if memory allocation failed In a situation where memory allocation fails, an invalid buffer address is stored. When this descriptor is used again, the system panics in the build_skb() function when accessing memory.
