CVE-2026-93100

A flaw was found in the Linux kernel's resctrl filesystem. A race condition exists in the rdtgroupknput function during the handling of rdtgroup structure reference counts. This allows a local attacker to trigger a use-after-free vulnerability, where memory is accessed after it has been...

CVE-2026-93100

CVE-2026-93100 is a use-after-free in the Linux kernel's fs/resctrl subsystem. The race occurs between rdtgroup_kn_put() (which decrements waitcount via atomic_dec_and_test() outside rdtgroup_mutex) and bulk teardown paths (free_all_child_rdtgrp() / rmdir_all_sub()) that hold the mutex. A concurr...
