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...
CVE-2026-43288
A flaw was found in the Linux kernel's ext4 filesystem. A local user can trigger a system panic, leading to a Denial of Service DoS, by mounting a specially crafted ext4 filesystem with specific quota and project options. This occurs because a per-CPU counter is accessed before it is properly...

CVE-2026-43401
The CVE-2026-43401 issue affects the Linux kernel's intel_pstate component. A NULL pointer dereference can occur in update_cpu_qos_request() when the code dereferences cpudata before validating the policy, especially on systems booted with nosmt where all_cpu_data[cpu] may be NULL for SMT sibling...
