Answer in brief
CVE-2026-74258 records a Unknown severity vulnerability in bpf: Guard __get_user acesss with access_ok for uprobe_multi data. 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.
A CVSS score is not reported in the current record. 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: bpf: Guard __get_user acesss with access_ok for uprobe_multi data As reported by sashiko [1] we need to use access_ok to check the user space data bounds before we use __get-user to get it.
