Description

In the Linux kernel, the following vulnerability has been resolved: scsi: smartpqi: Use is_kdump_kernel() to check for kdump The smartpqi driver checks the reset_devices variable to determine whether special adjustments need to be made for kdump. This has the effect that after a regular kexec reboot, some driver parameters such as max_transfer_size are much lower than usual. More importantly, kexec reboot tests have revealed memory corruption caused by the driver log being written to system memory after a kexec. Fix this by testing is_kdump_kernel() rather than reset_devices where appropriate.

Analysis

In the Linux kernel, the following vulnerability has been resolved: scsi: smartpqi: Use is_kdump_kernel() to check for kdump The smartpqi driver checks the reset_devices variable to determine whether. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. This Out-of-bounds Write vulnerability could allow attackers to write data beyond allocated buffer boundaries leading to code execution or crashes.

Technical Context

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes.

Affected Products

Linux Linux Kernel.

Remediation

A vendor patch is available. Apply the latest security update as soon as possible. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
