UBUNTU-CVE-2026-97943

In the Linux kernel, the following vulnerability has been resolved: x86/mm/pat: Acquire initmm write lock on collapse to avoid UAF x86 implements page attribute modification using its Change Page Attributes CPA mechanism. This tracks properties of ranges such as cache mode through x86 page...

CVE-2026-97943

The Linux kernel contains a vulnerability in the x86 architecture's Change Page Attributes (CPA) mechanism. Specifically, the cpa_collapse_large_pages() function can collapse kernel page table entries into huge page table entries and free the old page tables without holding necessary locks. This ...

CVE-2026-74672

A flaw was found in the Linux kernel. This vulnerability involves a use-after-free UAF error in the memory management subsystem, specifically during operations related to virtual memory vmalloc and page table dumping ptdump. A race condition can occur when the kernel attempts to free page tables...

CVE-2026-74599

A flaw was found in the Linux kernel's memory management subsystem. A race condition exists in the ptdump mechanism, specifically when ptdumpwalkpgd is used on non-initial memory management structures on x86 and arm64 architectures. This allows for a race between ptdump and kernel page table...

CVE-2026-74672

CVE-2026-74672 is a use-after-free vulnerability in the Linux kernel affecting both x86 and arm64 architectures. The root cause is a race condition between the ptdump page table walker and the vmap huge page table promotion logic: vmap frees lower page tables when promoting to huge leaf entries w...
