CVE-2026-43212

A flaw was found in the Linux kernel, specifically within the cpumaskofnode function on the LoongArch architecture. This function did not properly handle the NUMANONODE index, which is a valid input. This oversight could lead to unexpected system behavior or instability, potentially impacting...

EUVD-2026-27568

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Skip 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 uncore.c:1157...

CVE-2026-43212

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Make cpumaskofnode robust against NUMANONODE The arch definition of cpumaskofnode cannot handle NUMANONODE - which is a valid index - so add a check for this...

CVE-2026-43212

The CVE-2026-43212 entries involve the Linux kernel on LoongArch where cpumask_of_node() failed to handle NUMA_NO_NODE, which is a valid index. The root cause is an insufficient check in the arch-specific cpumask_of_node() implementation, leading to potential instability or incorrect behavior if ...
