CVE-2026-74518

A flaw was found in the Linux kernel. The allocatefileregionentries function, responsible for managing huge page memory regions, can suffer from list corruption. This occurs because the listsplice operation does not properly re-initialize a list head, allowing concurrent access to shared memory...

kernel: mm/huge_memory: update file PMD counter before folio_put()

A flaw was found in the Linux kernel's memory management, specifically within the huge page mechanism. When a huge page is split, the system updates a counter after releasing a reference to the memory. This timing issue can lead to the system attempting to read from memory that has already been...

CVE-2026-53154

A flaw was found in the Linux kernel's huge page hugetlb memory management. When an error occurs during the copying of huge pages, the system fails to properly restore the memory reservation. This can lead to a leak of the virtual memory area VMA reservation. A local attacker could exploit this b...
