CVE-2026-99160

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Do not show buffermeta for CPUs without a buffer The percpu/cpuN/buffermeta files are created for every possible CPU, but buffer-bufferscpu is only allocated once that CPU comes online. Reading the file of a CPU that...

CVE-2026-99160

The Linux kernel contains a vulnerability where reading the per_cpu/cpuN/buffer_meta file for a CPU that never came online results in a NULL pointer dereference of cpu_buffer within rbm_start(). This occurs because the files are created for all possible CPUs, while the buffer->buffers[cpu] mem...
