What is CVE-2026-68093?
This vulnerability was resolved in the Linux kernel's KVM SVM module, where a CPU hotplug cycle could cause an ASID collision if a vCPU was scheduled out. This could break memory isolation between virtual machines. Affected systems should apply the kernel update to fix the issue.
Azərbaycanca: Bu zəiflik Linux kernel-də KVM (Kernel-based Virtual Machine) SVM (Secure Virtual Machine) modulunda aşkarlanıb. CPU hotplug prosesi zamanı ASID (Address Space Identifier) toqquşması baş verə bilər ki, bu da virtual maşınların yaddaş təcridini poza bilər. Təsirə məruz qalan sistemlərdə kernel yeniləməsi tətbiq edilməlidir.
