CVE-2026-72309

A flaw was found in the Linux kernel's tracing/remotes component. This vulnerability occurs when a page allocation fails within the traceremoteallocbuffer function. Due to an unincremented CPU counter, a partially allocated buffer descriptor rbdesc is not properly freed, leading to a memory leak...

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 traceremoteallocbuffer 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...
