[PATCH OLK-6.6] media: uvcvideo: Fix crash during unbind if gpio unit is in use
by Zhang Kunbo 17 Mar '25

17 Mar '25

From: Ricardo Ribalda <ribalda(a)chromium.org> stable inclusion from stable-v6.6.78 commit 0b5e0445bc8384c18bd35cb9fe87f6258c6271d9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED4 CVE: CVE-2024-58079 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a9ea1a3d88b7947ce8cadb2afceee7a54872bbc5 upstream. We used the wrong device for the device managed functions. We used the usb device, when we should be using the interface device. If we unbind the driver from the usb interface, the cleanup functions are never called. In our case, the IRQ is never disabled. If an IRQ is triggered, it will try to access memory sections that are already free, causing an OOPS. We cannot use the function devm_request_threaded_irq here. The devm_* clean functions may be called after the main structure is released by uvc_delete. Luckily this bug has small impact, as it is only affected by devices with gpio units and the user has to unbind the device, a disconnect will not trigger this error.
