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. Fix that by always checking length limit on the oob buffer read and fill with 0xff when reaching the end of the buffer to the oob registers.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a potential out-of-bounds access issue in the Linux kernel's mtd: rawnand: brcmnand driver during out-of-band (oob) write operations. Specifically, when the oob buffer length is not a multiple of words, the oob write function may read beyond the end of the oob source buffer in its last iteration. The fix involves checking the length limit on the oob buffer read and filling with 0xff when the end of the buffer is reached to prevent out-of-bounds access.


How can this vulnerability impact me? :

This vulnerability could lead to out-of-bounds memory access during oob write operations in the affected Linux kernel driver. Such out-of-bounds reads may cause system instability, crashes, or potentially allow an attacker to read unintended memory areas, which could lead to information disclosure or other unpredictable behavior.
