The Linux kernel's qlcnic network driver is affected in versions from commit af19b49152bdb68fda894183e88096d6d1aa5c3d up to the fixes listed for each stable branch, and in kernel 2.6.34. The unified firmware ROM parser performed unchecked arithmetic on firmware-supplied fields and read beyond the firmware buffer for truncated images. The source gives few details on the exact trigger or impact. Upgrade to a kernel release that includes the fix, such as 6.1.191, 6.6.160, 6.12.110, or 6.18.52 or later in their respective series.
