CVE-2026-53108

CVE-2026-53108 concerns a race in PowerPC64 (book3s64) PMD migration handling during unmap vs move_pages. The vulnerability arises when a PMD migration entry is created by migrate_pages while an munmap occurs, hitting a VM_BUG_ON in pmdp_huge_get_and_clear_full. The Linux kernel patch (commit a30...

Linux move_pages_huge_pmd Heap Buffer Overflow DoS

The vulnerability of the movepageshugepmd function in the Linux operating system is related to the swapping of pointers. Exploiting this vulnerability could allow an attacker to trigger a service failure...

CVE-2026-31397

A flaw was found in the Linux kernel's memory management subsystem, specifically within the movepageshugepmd function. A local user could exploit a NULL pointer dereference when handling huge zero pages, which can lead to a system crash and a Denial of Service DoS. Furthermore, improper...
