EUVD-2026-27378

In the Linux kernel, the following vulnerability has been resolved: x86-64: rename misleadingly named 'copyusernocache' function This function was a masterclass in bad naming, for various historical reasons. It claimed to be a non-cached user copy. It is literally neither of those things. It's a...

CVE-2026-43073

CVE-2026-43073 stems from a misnamed x86-64 kernel routine __copy_user_nocache(), a non-temporal destination copy with exception handling that is not actually a pure user-kernel copy and has complex alignment behavior. The fix renames the function and normalizes the prototype so callers perform p...

CVE-2026-35233

An unprivileged attacker can craft a user-space process with a malicious ELF binary containing an out-of-range shlink field. When root-level dtrace attaches to -- or instruments -- that process via dtrace -p , pid probes, or USDT, the ELF parser reads heap memory beyond the allocated section cach...
