CVE-2026-110830

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can trigger a Denial of Service DoS by sending repeated serial device creation requests when serial port redirection is enabled. Because FreeRDP fails to release previous communication handles before allocating new ones,...

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.2.10-1.1 Description An issue exists in the Bluetooth hci qca module where the system may attempt to write to a serial port after it has been closed. This occurs when hci uart close closes the serdev port...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix for panic due to PSLVERR When the PSLVERRRESPEN parameter is set to 1, the device generates an error response if an attempt is made to read an empty RBR Receive Buffer Register while the FIFO is enabled. In...

CVE-2026-97481

A flaw was found in the Linux kernel's 8250 serial port driver. An attacker communicating over the serial interface can cause a Denial of Service DoS by flooding the port with messages during the system startup phase. Due to missing error handling for First-In, First-Out FIFO buffer interrupts, t...

ROS-20260923-73-0082

The vulnerability of the arcserialprobe function in the drivers/tty/serial/arcuart.c file of the console TTY driver in the Linux kernel’s serial port module is related to improper memory release. Exploiting this vulnerability could allow an attacker to cause a service failure...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Reinit port-pm on port-specific driver unbind When we unbind a serial port via a hardware-specific 8250 driver, the generic serial8250 driver takes over control of the port. Approximately 10 seconds later, an oops...

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

In the Linux kernel, the following vulnerability has been resolved: serial: 8250port: Check IRQ data before use If the leaf driver wishes to use IRQ polling irq = 0, and the IIR register indicates that an interrupt occurred in the 8250 hardware, the IRQ data can be NULL. In such cases, we need to...

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

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: omap: Do not skip resource freeing if pmruntimeresumeandget fails. Returning an error code from .remove causes the driver core to emit a rather useless error message: remove callback returned a non-zero value. This...

Astra Linux – Vulnerability in Linux 5.10, Linux

KGDB and KDB allow read and write access to kernel memory, and therefore should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger, so it is important that the debugger respects the lockdown mode when/if it is triggered. CVSS 3.1 Base Score: 6.7...

Astra Linux – Vulnerability in Chromium

In the Blink Serial API in Google Chrome, a memory access out of bounds was allowed before version 97.0.4692.71. This allowed a remote attacker to perform a memory read through a crafted HTML page and a virtual serial port driver...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fixed an oops in port-pm when calling uartchangepm Unloading a hardware-specific 8250 driver may cause an error “Unable to handle kernel paging request at virtual address” about ten seconds after unloading the drive...

Linux TTY Driver Heap Buffer Overflow DoS

The vulnerability of the dw8250probe function in the drivers/tty/serial/8250/8250dw.c file of the console TTY driver in the Linux kernel’s serial port module is related to the assignment of a pointer with an expired lifetime. Exploiting this vulnerability could allow an attacker to compromise the...
