[PATCH openEuler-22.03-LTS-SP1] HID: wacom: fix when get product name maybe null pointer
by Tengda Wu 31 Dec '24

31 Dec '24

From: WangYuli <wangyuli(a)uniontech.com> stable inclusion from stable-v5.10.231 commit 5912a921289edb34d40aeab32ea6d52d41e75fed category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAPQ CVE: CVE-2024-56629 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 59548215b76be98cf3422eea9a67d6ea578aca3d upstream. Due to incorrect dev->product reporting by certain devices, null pointer dereferences occur when dev->product is empty, leading to potential system crashes. This issue was found on EXCELSIOR DL37-D05 device with Loongson-LS3A6000-7A2000-DL37 motherboard.

From: WangYuli <wangyuli(a)uniontech.com> stable inclusion from stable-v5.10.231 commit 5912a921289edb34d40aeab32ea6d52d41e75fed category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAPQ CVE: CVE-2024-56629 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 59548215b76be98cf3422eea9a67d6ea578aca3d upstream. Due to incorrect dev->product reporting by certain devices, null pointer dereferences occur when dev->product is empty, leading to potential system crashes. This issue was found on EXCELSIOR DL37-D05 device with Loongson-LS3A6000-7A2000-DL37 motherboard.
