CVE-2022-49755 (GCVE-0-2022-49755)

Vulnerability from cvelistv5 – Published: 2025-03-27 16:43 – Updated: 2025-05-04 08:44

Title

usb: gadget: f_fs: Prevent race during ffs_ep0_queue_wait

Summary

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_fs: Prevent race during ffs_ep0_queue_wait While performing fast composition switch, there is a possibility that the process of ffs_ep0_write/ffs_ep0_read get into a race condition due to ep0req being freed up from functionfs_unbind. Consider the scenario that the ffs_ep0_write calls the ffs_ep0_queue_wait by taking a lock &ffs->ev.waitq.lock. However, the functionfs_unbind isn't bounded so it can go ahead and mark the ep0req to NULL, and since there is no NULL check in ffs_ep0_queue_wait we will end up in use-after-free. Fix this by making a serialized execution between the two functions using a mutex_lock(ffs->mutex).

However, the functionfs_unbind isn\u0027t\nbounded so it can go ahead and mark the ep0req to NULL, and since there\nis no NULL check in ffs_ep0_queue_wait we will end up in use-after-free.\n\nFix this by making a serialized execution between the two functions using\na mutex_lock(ffs-\u003emutex)."
