Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Linux kernel versions from 4.8 before the fixes listed for the scsi: qla2xxx driver are affected. The qla2xxx driver's dport diagnostics path returns uninitialized kernel heap memory to user space through the options and unused fields of its response buffer. A local user who can issue the diagnostics request can read that heap data. Upgrade to a fixed kernel release for your branch, such as 5.10.273, 5.15.224, 6.1.191, or 6.6.160 or later. The source gives few details on the exact fixed version for other branches.
