CVE-2026-43045

A flaw was found in the Linux kernel's mshv module. Incorrect error handling in the mshvregionpin function can lead to memory corruption. This occurs when the pinuserpagesfast operation returns a partial pin count, causing the system to use incompletely pinned memory regions. This issue can also...
