CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's resource control (resctrl) subsystem, specifically involving the handling of Resource Management IDs (RMIDs) for pseudo-locked groups. The issue arises from a double-free condition that can lead to memory corruption, potentially allowing an attacker to exploit this flaw for arbitrary code execution or system instability. Linux administrators and developers working with kernel-level resource management should prioritize addressing this vulnerability to ensure system integrity and security.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: fs/resctrl: Fix double-add of pseudo-locked region's RMID to free list A pseudo-locked group's RMID is freed when it is created. On unmount rmdir_all_sub() unconditionally frees all RMID of all groups, resulting in a double-free of the pseudo-locked group's RMID. The consequence of this is that the original free results in the pseudo-locked group's RMID being added to the rmid_free_lru linked list and the second free then attempts to add the same RMID entry to the rmid_free_lru again. Do not double-free a pseudo-locked group's RMID.
