CyberRota Analysis
AI-GeneratedA vulnerability exists in the Linux kernel's media subsystem, specifically in the `rzv2h-ivc` component, where concurrent access to a buffer list is not properly synchronized due to a missing spinlock during buffer removal. This oversight can lead to race conditions, potentially resulting in data corruption or system instability. Organizations using affected Linux distributions should prioritize patching this vulnerability to mitigate the risk of exploitation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: media: rzv2h-ivc: Fix concurrent buffer list access The list of buffers (`rzv2h_ivc::buffers.queue`) is protected by a spinlock (`rzv2h_ivc::buffers.lock`). However, in `rzv2h_ivc_transfer_buffer()`, which runs in a separate workqueue, the `list_del()` call is executed without holding the spinlock, which makes it possible for the list to be concurrently modified Fix that by removing a buffer from the list in the lock protected section. [assign ivc->buffers.curr in critical section as reported by Barnabas]
