CVE-2026-72309

tracing/remotes: Fix leak in trace_remote_alloc_buffer() error path

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

tracing/remotes: Fix leak in trace_remote_alloc_buffer() error path

If page allocation fails in trace_remote_alloc_buffer(), desc->nr_cpus
is not yet incremented for the current CPU. As a consequence, on error,
half-allocated rb_desc will not be freed in trace_remote_free_buffer().

Increment desc->nr_cpus as soon as the first allocation for the current
CPU has succeeded.
