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...

CVE-2026-23472

Summary: A Linux kernel vulnerability in the serial core (CVE-2026-23472) arises when handling PORT_UNKNOWN with a NULL transmit buffer, where uart_write_room() can report available space inconsistently with uart_write() , causing an infinite loop in drivers that rely on tty_write_room() to decid...
