CVE-2026-72309

Summary
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.
