Linux Kernel ST LSM6DSX IMU Driver FIFO Read Lockup Vulnerability

A vulnerability in the Linux kernel's IIO IMU ST LSM6DSX driver can lead to a potential lockup issue. The problem arises in the 'st_lsm6dsx_read_fifo' function, where the 'pattern_len' parameter being zero can cause the function to enter an infinite loop if the device FIFO is not empty.

Impact

Exploitation of this vulnerability can cause a system hang, leading to a denial of service condition where the affected process or thread becomes unresponsive.
