CVE-2026-23472

A flaw was found in the Linux kernel's serial core component. An inconsistency between the uartwriteroom and uartwrite functions, specifically when handling PORTUNKNOWN serial ports with a NULL transmit buffer, can lead to an infinite loop. This allows a local user or process to trigger a system...
