CVE-2026-98883 serial: 8250_port: recognize UPIO_AU

In the Linux kernel, the following vulnerability has been resolved: serial: 8250port: recognize UPIOAU My MIPS Alchemy systems generate the following warning during probe of the 8250 driver: WARNING: drivers/tty/serial/8250/8250port.c:462 at setiofromupio+0xfc/0x124, CPU0: swapper/0/1 Unsupported...

CVE-2026-98883

The Linux kernel contains a vulnerability in the 8250 serial driver where the set_io_from_upio() function fails to recognize UPIO_AU (type 4) UART types. This causes an "Unsupported UART type 4" warning during the probe of the 8250 driver, specifically observed on MIPS Alchemy systems. The fix in...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions prior to 6.18.53. This vulnerability stems from the failure to recognize UPIOAU type 4 UART types within setiofromupio. As a result, warnings may be generated when the 8250 driver attempts to detect unsupported UART types...

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 hardware-specific 8250 driver, the generic serial8250 driver takes over the port. About 10 seconds later, an oops occurs. This can result in...

Astra Linux – vulnerability in linux-5.10, linux-5.15, linux-6.1

In the Linux kernel, the following vulnerability has been resolved: serial: 8250omap: Implementation of Errata i2310 According to Errata i23100, an erroneous timeout can be triggered; if this Erroneous interrupt is not cleared, it may lead to a storm of interrupts. Therefore, the Errata i2310...

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...
