Description
In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: brcmnand: Fix potential out-of-bounds access in oob write When the oob buffer length is not in multiple of words, the oob write function does out-of-bounds read on the oob source buffer at the last iteration.
