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...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fixed PM usagecount for console handover When the console is enabled, univ8250consolesetup calls serial8250consolesetup before .dev is set to uartport. As a result, pmruntimegetsync will not be called. Later, when t...

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...

CVE-2026-97480

A flaw was found in the Linux kernel's 8250 serial driver. During serial port registration for devices lacking an associated parent device, the driver attempts to access device properties without verifying that the device pointer is valid. This condition leads to a NULL pointer dereference, which...
