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...

In the Linux kernel, the following vulnerability has been resolved: tty: serial: 8250: protect against NULL uart-port.dev in register serial8250register8250port conditionally copies uart-port.dev from up-port.dev only when up-port.dev is non-NULL: if up-port.dev uart-port.dev = up-port.dev; ... S...

PT-2026-79658

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the NXP LPC32xx UART PORT LPC3220 where an RX character-timeout interrupt can be latched while the RX FIFO is empty. In this state, the Interrupt Identification Regist...

DEBIAN-CVE-2022-49613

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix PM usagecount for console handover When console is enabled, univ8250consolesetup calls serial8250consolesetup before .dev is set to uartport. Therefore, it will not call pmruntimegetsync. Later, when the actual...

CVE-2022-49392 serial: 8250_aspeed_vuart: Fix potential NULL dereference in aspeed_vuart_probe

In the Linux kernel, the following vulnerability has been resolved: serial: 8250aspeedvuart: Fix potential NULL dereference in aspeedvuartprobe platformgetresource may fail and return NULL, so we should better check it's return value to avoid a NULL pointer dereference...

kernel: serial: 8250: Reinit port->pm on port specific driver unbind

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. After that we see an oops about 10 seconds later. This can...
