A critical vulnerability known as Bad Epoll (CVE-2026-46242) has been identified in the Linux kernel, involving a use-after-free race condition. This flaw allows local users with standard permissions to escalate their privileges to root, effectively gaining full administrative control over the system. The vulnerability poses a significant risk to a wide range of platforms, including Linux-based servers, desktops, and Android mobile devices. Security researchers have confirmed that the exploit is reliable, and while a patch has been released, users are urged to update their kernels immediately to mitigate the threat of unauthorized system takeovers.
