SUSE CVE-2026-93181
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...
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...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Linux kernel regarding the ordering of reference and unreference operations within the perf/x86/intel/uncore component. In the uncore event cpu online function,...
Linux Kernel Security Vulnerabilities
The Linux kernel version 6.11 contains security vulnerabilities. These vulnerabilities stem from the improper call order of uncorebox and its references in perf/x86/intel/uncore. This leads to the box not being initialized and incorrect reference counts, potentially causing abnormal resource...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Skipping the discovery table for offline dies This warning can be triggered if NUMA is disabled and the system boots with fewer CPUs than the number of CPUs in die 0. WARNING: CPU: 9 PID: 7257 at...
CVE-2026-43344
A flaw was found in the Linux kernel's performance monitoring unit perf/x86/intel/uncore subsystem. This vulnerability arises from incorrect die ID initialization and lookup, particularly when certain CPUs are offline or when Non-Uniform Memory Access NUMA is disabled. As a consequence, performan...
