[PATCH openEuler-1.0-LTS] usb: gadget: f_fs: Prevent race during ffs_ep0_queue_wait
by Guo Mengqi 25 Apr '25

25 Apr '25

From: Udipto Goswami <quic_ugoswami(a)quicinc.com> stable inclusion from stable-v4.19.272 commit e9036e951f93fb8d7b5e9d6e2c7f94a4da312ae4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBWVWG CVE: CVE-2022-49755 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 6a19da111057f69214b97c62fb0ac59023970850 ] 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).
