[PATCH openEuler-1.0-LTS] media: venus: fix use after free bug in venus_remove due to race condition

From: Zheng Wang <zyytlz.wz(a)163.com> stable inclusion from stable-v5.10.227 commit 60b6968341a6dd5353554f3e72db554693a128a5 bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRCM CVE: CVE-2024-49981 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c5a85ed88e043474161bbfe54002c89c1cb50ee2 upstream. in venus_probe, core->work is bound with venus_sys_error_handler, which is used to handle error. The code use core->sys_err_done to make sync work. The core->work is started in venus_event_notify. If we call venus_remove, there might be an unfished work. The possible sequence is as follows: CPU0 CPU1 |venus_sys_error_handler venus_remove | hfi_destroy | venus_hfi_destroy | kfree(hdev); | |hfi_reinit |venus_hfi_queues_reinit |//use hdev Fix it by canceling the work in venus_remove.

It added one to uart_shutdown(), so the commit assumes, uport can be NULL in there. But right after that protection, there is an unprotected "uart_port_dtr_rts(uport, false);" call. That is invoked only if HUPCL is set, so I assume that is the reason why we do not see lots of these reports. Or it cannot be NULL at this point at all for some reason :P. Until the above is investigated, stay on the safe side and move this dereference to the if too. I got this inconsistency from Coverity under CID 1585130. Thanks.
