The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tracepoint: balance regfunc on funcadd failure in tracepointaddfunc When a tracepoint goes through the 0 - 1 transition, tracepointaddfunc invokes the subsystem...

CVE-2026-46196

A flaw was found in the Linux kernel. When a tracepoint a mechanism for dynamic instrumentation is registered, a failure during the probe installation process can lead to the registration's side effects persisting without a corresponding probe. This can cause a Denial of Service DoS by leaving...
