Linux Kernel Security Vulnerabilities

The Linux kernel version 3.4 contains security vulnerabilities. These vulnerabilities stem from an improper order of driver during the uninstallation of the USB serial driver module. I/O operations were not stopped before unbinding the port, which may lead to reuse of freed resources after data...

Linux Kernel Security Vulnerabilities

The Linux kernel version 2.6.26 contains security vulnerabilities. These vulnerabilities stem from race conditions in the tty ioctl and hang-up operations within the USB serial driver. Access to port driver data or hardware occurs without checking whether the port is already hung up. This could...

Linux Kernel Security Vulnerabilities

The Linux kernel version 2.6.30 has a security vulnerability. This vulnerability stems from a race condition in the USB serial driver when the port is removed. The processing program may access data from the port driver that has been released, leading to reutilization of the released port...

In the Linux kernel, the following vulnerability has been resolved: serial: 8250dw: Unregistering the 8250 port if clknotifierregister fails The dw8250probe function registers the 8250 port via serial8250register8250port. If the device has a clock, a clock notifier is also registered. If...

Astra Linux – vulnerability in linux-5.15

In the Linux kernel, the following vulnerability has been resolved: tty: serial: imx: disable Ageing Timer interrupt request irq There might be pending USR interrupts before requesting the IRQ; however, uartaddoneport has not yet been executed, resulting in a kernel panic: 0.795668 Unable to hand...

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...

kernel: USB: serial: io_ti: fix heap overflow in get_manuf_info()

A flaw was found in the Linux kernel's ioti USB serial driver. A malicious USB device, when plugged into a host running this driver, can exploit a heap overflow vulnerability in the getmanufinfo function. This occurs because the driver does not properly validate the size of data read from the...
