Description OSIDB Bzimport 2025-04-01 16:05:11 UTC 
In the Linux kernel, the following vulnerability has been resolved:

scsi: qla1280: Fix kernel oops when debug level > 2

A null dereference or oops exception will eventually occur when qla1280.c
driver is compiled with DEBUG_QLA1280 enabled and ql_debug_level > 2.  I
think its clear from the code that the intention here is sg_dma_len(s) not
length of sg_next(s) when printing the debug info.
