Thus require write permission. Depending on the hardware MEMLOCK might even be write-once, e.g. for SPI-NOR flashes with their WP# tied to GND. OTPLOCK is always write-once.</p> <p>MEMSETBADBLOCK modifies the bad block table.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>mtd: require write permissions for locking and badblock ioctls</p> <p>MEMLOCK, MEMUNLOCK and OTPLOCK modify protection bits.
