Linux Kernel Vulnerability in vsp1 Driver

CVE-2023-53497

What is CVE-2023-53497?

A vulnerability in the vsp1 driver of the Linux kernel can lead to system crashes. The bug arises from a recent change in how the driver checks for the start of streaming operations. Instead of confirming that streaming has been initiated, the function erroneously believes it has, due to premature updates to the streaming state. This misjudgment results in kernel NULL pointer dereferences, causing the driver to fault and potentially crash the system. Immediate attention to updating the kernel version can prevent such incidents.
