Answer in brief
CVE-2022-49356 records a Critical severity (CVSS 9.8) vulnerability in SUNRPC: Trap RDMA segment overflows. 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 9.8. 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: SUNRPC: Trap RDMA segment overflows Prevent svc_rdma_build_writes() from walking off the end of a Write chunk's segment array. Caught with KASAN. The test that this fix replaces is invalid, and might have been left over from an earlier prototype of the PCL work.
