  1. Linux DRM CVE-2024-42081: Tiny NULL Check Prevents Kernel Oops

    A small defensive change in the Linux kernel’s DRM subsystem — a missing NULL check in the xe_devcoredump path — was assigned CVE-2024-42081 and patched in mid‑2024; while the fix is trivial in code, the operational impact is real: a NULL assignment in kernel space can yield an immediate kernel...

  2. Linux Kernel DRM XE Patch Fixes Arithmetic Overflow in Page Size Calculation

    The Linux kernel patch credited to CVE‑2024‑42066 fixes a subtle but important arithmetic bug in the DRM XE driver: the code now explicitly casts tbo->page_alignment to a 64‑bit unsigned type (u64) before performing a bit shift used to compute min_page_size, removing a possible integer overflow...
