CyberRota Analysis

AI-Generated

The vulnerability affects the Linux kernel's fuse-uring component, where improper handling of the `queue->stopped` state can lead to race conditions. This could allow multiple threads to access and modify the `struct fuse_req` concurrently, potentially leading to memory corruption or application crashes. Organizations using Linux systems, particularly those leveraging fuse-uring for file system operations, should prioritize patching this issue to mitigate the risk of exploitation.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: fuse-uring: Avoid queue->stopped races and set/read that value under lock There are several readers of queue->stopped that check the value under lock, but fuse_uring_commit_fetch() did not and actually the value was not set under the lock in fuse_uring_abort_end_requests() either. Especially in fuse_uring_commit_fetch it is important to check under a lock, because due to races 'struct fuse_req' might be freed with fuse_request_end, but another thread/cpu might already do teardown work.
