Overview

Affected versions of this package are vulnerable to Improper Cleanup on Thrown Exception due to incorrect handling of cgroup reservation and uncharge logic in the alloc_hugetlb_folio process. An attacker can bypass enforced hugepage reservation quotas and disrupt memory accounting by repeatedly allocating and freeing hugepages through hugetlbfs mappings without reservations, leading to resource exhaustion and denial of service for other workloads.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
