Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a race condition in the Linux kernel's mmu notification mechanism. This mechanism is used to invalidate memory ranges, and depending on the number of iterations, different memory ranges would be invalidated. The vulnerability can be exploited to impact the confidentiality and availability of protected information. A patch has been applied to move the mmu notification mechanism inside the mm lock to prevent the race condition. The patch also removes a warning related to the kvm mmu notifier change pte function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
