Created: Oct 29, 2026 Updated: Nov 4, 2026

Resolved Date: Nov 3, 2026

Found In Version: 10.23.30.2

Fix Version: 10.23.30.9

Severity: Standard

Applicable for: Wind River Linux LTS 23

Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:  ring-buffer: Do not show buffer_meta for CPUs without a buffer  The per_cpu/cpuN/buffer_meta files are created for every possible CPU, but buffer->buffers[cpu] is only allocated once that CPU comes online. Reading the file of a CPU that never came online dereferences a NULL cpu_buffer in rbm_start().  Fail the open with -ENODEV when the CPU has no buffer, as the other per CPU ring buffer interfaces do.
