Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: serial: imx: fix tx statemachine deadlock When using the serial port as a RS485 port, the tx statemachine is used to control the RTS pin to drive the RS485 transceiver’s TXEN pin. When the TTY port is closed mid-transmission e.g....

SUSE CVE-2026-74652

In the Linux kernel, the following vulnerability has been resolved: serial: amba-pl011: cancel RS485 hrtimers after freeing IRQ The RS485 trigger hrtimers are embedded in the devm-managed port and can fire after it is freed. The IRQ handler can arm a timer, so free the IRQ first and then cancel...

CVE-2026-74652

A flaw was found in the Linux kernel's amba-pl011 serial driver. The RS485 trigger high-resolution timers hrtimers can fire after the device management devm-managed port is freed. This occurs because the timers are not properly canceled before the interrupt request IRQ is freed, allowing a...
