CVE-2025-40230

CVE-2025-40230 covers a Linux kernel issue where memory error injections on a Transparent Huge Page (THP) mapped to userspace could trigger a kernel panic. The root cause: during THP splitting, the kernel reads THP pages to identify zeropage mappings while a memory failure is being handled, which...

CVE-2024-26674

CVE-2024-26674 affects the Linux kernel x86/mm code, specifically a fixup path for get_user()/put_user(). In kernel builds >= 6.4 memory-error-injection can trigger a machine-check and panic due to a revert from _ASM_EXTABLE_UA() to a more generic fixup type. The issue arose when MCA handling ...
