What to do

AI-suggested

A fix has been implemented to decrement the nfeeds counter when start_streaming fails, ensuring the driver state remains consistent and preventing memory leaks. Users should apply the official Linux kernel updates that include this fix once available.

Description

A vulnerability in the Linux kernel's vidtv driver causes state corruption and memory leaks when the start_streaming function fails. The nfeeds counter is incorrectly incremented without being decremented on failure, leading to inconsistent driver state and resource leaks.
