HID: check empty report_list in bigben_probe()
stable inclusion from stable-v5.10.166 commit 20fd4598762e2d717deb64ef028e6f5f587ac2a6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6KCIO CVE: CVE-2023-1073 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=20fd4598762e2d717deb64ef028e6f5f587ac2a6 -------------------------------- Add a check for empty report_list in bigben_probe(). The missing check causes a type confusion when issuing a list_entry() on an empty report_list. The problem is caused by the assumption that the device must have valid report_list. While this will be true for all normal HID devices, a suitably malicious device can violate the assumption.
