  "description": "In the Linux kernel, the following vulnerability has been resolved:  mshv: Fix use-after-free in mshv_map_user_memory error path  In the error path of mshv_map_user_memory(), calling vfree() directly on the region leaves the MMU notifier registered. When userspace later unmaps the memory, the notifier fires and accesses the freed region, causing a use-after-free and potential kernel panic.  Replace vfree() with mshv_partition_put() to properly unregister the MMU notifier before freeing the region.",
