CVE-2026-45857 Details
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: csiostor: Fix dereference of null pointer rn The error exit path when rn is NULL ends up deferencing the null pointer rn via the use of the macro CSIO_INC_STATS. Fix this by adding a new error return path label after the use of the macro to avoid the deference.
A null pointer dereference vulnerability has been identified in the Linux kernel's SCSI CSIOSTOR driver. This issue arises when the 'rn' pointer is NULL, leading to a dereference via the CSIO_INC_STATS macro. The vulnerability has been addressed by introducing a new error return path label to prevent the null pointer dereference.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. The commit addressing this issue is available in the Linux kernel stable tree.
