CVE-2026-23432

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