Title

Xen存在多个内存泄露漏洞

Description

Xen是英国剑桥大学开发的一款开源的虚拟机监视器产品。该产品能够使不同和不兼容的操作系统运行在同一台计算机上，并支持在运行时进行迁移，保证正常运行并且避免宕机。 Xen 4.0版本至4.6.x版本中存在多个内存泄露漏洞，这些漏洞源于程序使用XEN_DOMCTL_max_vcpus超级调用分配vcpu指针数组内存；使用XENOPROF_get_buffer和XENOPROF_set_passive超级调用分配xenoprofile state vcpu指针数组内存。本地攻击者可利用这些漏洞，以特定的权限造成拒绝服务（内存损坏）。

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
