Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from improper handling of VMPAT on fork failure in copypagerange, which could lead to a resource leak...

PT-2025-16730

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.12.0-rc5+ Description A vulnerability in the Linux kernel has been resolved, related to the handling of VM PAT when fork fails in copy page range. If track pfn copy fails, the dst VMA is added to the maple tree...

The vulnerability of the __unmap_hugepage_range() function in the Linux kernel memory manager allows a hacker to trigger a system failure.

The vulnerability of the unmaphugepagerange function in the mm/hugetlb.c file of the Linux kernel’s memory manager is related to an incorrect check in the code that returns vmaneedsreservation. Exploiting this vulnerability could allow an attacker to trigger a service failure...
