Linux Kernel ST LSM6DSX IMU Driver Infinite Loop Vulnerability in Tagged FIFO Read

A vulnerability in the Linux kernel's IIO IMU ST LSM6DSX driver could lead to a potential lockup. The issue arises in the 'st_lsm6dsx_read_tagged_fifo' function, where the code may enter an infinite loop if the 'pattern_len' is zero and the device's FIFO is not empty.

Impact

Exploitation of this vulnerability can cause the system to hang indefinitely while the affected function is processing, potentially leading to a denial of service.
