[PATCH OLK-5.10] usb: gadget: udc: renesas_usb3: Fix use after free bug in renesas_usb3_remove due to race condition
by Jialin Zhang 28 Jun '23

28 Jun '23

From: Zheng Wang <zyytlz.wz(a)163.com> mainline inclusion from mainline-v6.4-rc1 commit 2b947f8769be8b8181dc795fd292d3e7120f5204 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I7EDYS CVE: CVE-2023-35828 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In renesas_usb3_probe, role_work is bound with renesas_usb3_role_work. renesas_usb3_start will be called to start the work. If we remove the driver which will call usbhs_remove, there may be an unfinished work. The possible sequence is as follows: CPU0 CPU1 renesas_usb3_role_work renesas_usb3_remove usb_role_switch_unregister device_unregister kfree(sw) //free usb3->role_sw usb_role_switch_set_role //use usb3->role_sw The usb3->role_sw could be freed under such circumstance and then used in usb_role_switch_set_role. This bug was found by static analysis. And note that removing a driver is a root-only operation, and should never happen in normal case. But the root user may directly remove the device which will also trigger the remove function. Fix it by canceling the work before cleanup in the renesas_usb3_remove.

If we remove the module or device which will call saa7134_finidev to make cleanup, there may be a unfinished work. The possible sequence is as follows, which will cause a typical UAF bug. Fix it by canceling the timer works accordingly before cleanup in saa7134_finidev.
