[PATCH openEuler-1.0-LTS] scsi: qla4xxx: Prevent a potential error pointer dereference
by Zhang Qilong 28 Oct '25

28 Oct '25

From: Dan Carpenter <dan.carpenter(a)linaro.org> stable inclusion from stable-v5.4.297 commit d0225f41ee70611ca88ccb22c8542ecdfa7faea8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICWO34 CVE: CVE-2025-39676 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 9dcf111dd3e7ed5fce82bb108e3a3fc001c07225 ] The qla4xxx_get_ep_fwdb() function is supposed to return NULL on error, but qla4xxx_ep_connect() returns error pointers. Propagating the error pointers will lead to an Oops in the caller, so change the error pointers to NULL.
