CVE-2026-93181

CVE-2026-93181 affects the Linux kernel in the perf/x86/intel/uncore subsystem. The root cause is an incorrect call ordering: in the CPU online path, uncore_box_ref() was invoked before uncore_change_context(), so the gate on box->cpu >= 0 always failed and the uncore box was never initiali...

CVE-2026-93181: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix uncorebox ref/unref ordering In uncoreeventcpuonline, uncoreboxref was called before uncorechangecontext. uncoreboxref gates on box-cpu = 0, but box-cpu is still -1 at that point because...
