Threats tagged 'ghsa-x642-fqm9-qj5q'

A use-after-free vulnerability was identified and resolved in the Linux kernel's resctrl filesystem component, specifically in the rdtgroup_kn_put() function. The flaw arises from a race condition between two paths that free rdtgroup structures, potentially leading to double free or use-after-free scenarios. The fix involves synchronizing reference count decrement and flag inspection under a mutex to prevent concurrent access issues.
