CVE-2023-53451 Details
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix potential NULL pointer dereference Klocwork tool reported 'cur_dsd' may be dereferenced. Add fix to validate pointer before dereferencing the pointer.
A potential NULL pointer dereference vulnerability has been identified in the Linux kernel's QLogic Fibre Channel driver (qla2xxx) within the SCSI subsystem. This issue affects the stable versions of the Linux kernel. The vulnerability arises because the 'cur_dsd' pointer may be dereferenced without proper validation, as reported by the Klocwork static analysis tool. This could lead to undefined behavior or a system crash.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The official Linux kernel Git repository includes the necessary patches.
