CVE-2026-74599

CVE-2026-74599 is a race condition in the Linux kernel 's mm/ptdump subsystem. Previous fixes established that kernel page table freeing occurs while holding an mmap read lock on init_mm , but x86 and arm64 architectures can perform a ptdump over a non-init_mm via ptdump_walk_pgd(). Since kernel ...

CVE-2026-74524

A flaw was found in the Linux kernel. When performing memory hot-remove operations on systems using RISC-V architecture, an out-of-bounds page-table walk can occur. This issue arises because the system attempts to access memory outside of its designated boundaries, potentially leading to a kernel...

CVE-2026-72362

A flaw was found in the Linux kernel's drm/xe/pt module. This vulnerability arises when the page-table walk framework provides a null pointer for unpopulated entries, and the xeptzapptesentry function attempts to access this null pointer without prior validation. This improper handling can lead t...
