Description OSIDB Bzimport 2025-05-20 18:02:19 UTC 
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.
