- Summary
- tracing/remotes: Fix leak in trace_remote_alloc_buffer() error path
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
tracing/remotes: Fix leak in traceremotealloc_buffer() error path
If page allocation fails in traceremoteallocbuffer(), desc->nrcpus is not yet incremented for the current CPU. As a consequence, on error, half-allocated rbdesc will not be freed in traceremotefreebuffer().
Increment desc->nr_cpus as soon as the first allocation for the current CPU has succeeded.
