CVE-2026-98057

Estado: En análisisSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

ring-buffer: Add checking nr_subbufs to persistent ring buffer validation

Sashiko reported that the code was using meta->nr_subbufs without making sure that it matched the nr_pages + 1 on data that was assuming the two were the same.

Add a check to the persistent ring buffer validation code to make sure that the saved nr_subbufs matches what we expect.
