Not availableNo severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
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.
