CVE-2023-54092 (CNNVD-202512-4482)
中文标题:
Linux kernel 安全漏洞
英文标题:
KVM: s390: pv: fix index value of replaced ASCE
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于替换的ASCE索引值错误，可能导致地址传递错误和有效性拦截。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pv: fix index value of replaced ASCE The index field of the struct page corresponding to a guest ASCE should be 0. When replacing the ASCE in s390_replace_asce(), the index of the new ASCE should also be set to 0. Having the wrong index might lead to the wrong addresses being passed around when notifying pte invalidations, and eventually to validity intercepts (VM crash) if the prefix gets unmapped and the notifier gets called with the wrong address.
