CVE-2026-99238 tracing: Hold trace_types_lock when updating modules in persistent instances
PublishedHighCVSS 7.8 EPSS 0.12%In the Linux kernel, the following vulnerability has been resolved: tracing: Hold trace_types_lock when updating modules in persistent instances trace_module_record() walks ftrace_trace_arrays from the module notifier without trace_types_lock. A concurrent rmdir of an instance re...
