🟠 《高危安全漏洞：CVE-2026-53200》

CVSS 评分: 高危（8.8）　　状态: Received　　发布时间: 2026-06-25

英文原文描述

In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: nv: Fix handling of XN[0] when !FEAT_XNX

XN has already been extracted from its bitfield position so using
FIELD_PREP() on the mask that clears XN[0] is completely broken, having
the effect of unconditionally granting execute permissions...

Fix the obvious mistake by manipulating the right bit.
