[PATCH OLK-6.6] HID: uclogic: Add NULL check in uclogic_input_configured()
by ZHENG Xinyu 25 Jun '25

25 Jun '25

From: Henry Martin <bsdhenrymartin(a)gmail.com> stable inclusion from stable-v6.6.92 commit ad6caaf29bc26a48b1241ce82561fcbcf0a75aa9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICG6RJ CVE: CVE-2025-38007 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- devm_kasprintf() returns NULL when memory allocation fails. Currently, uclogic_input_configured() does not check for this case, which results in a NULL pointer dereference. Add NULL check after devm_kasprintf() to prevent this issue.
