The vulnerability of the Linux operating system’s kernel driver allows a hacker to trigger a service failure.

The vulnerability of the Linux operating system’s MTD driver kernel relates to the assignment of a null pointer in the functions registermtdblktrans and blktransnotifyadd in the drivers/mtd/mtdblkdevs.c module. Exploiting this vulnerability could allow an attacker to trigger a service failure...

CVE-2021-47055

A flaw was found in the Linux Kernel, requiring write permissions for locking and badblock ioctls, as they modify protection bits...

CVE-2021-47055

In the Linux kernel, the following vulnerability has been resolved: mtd: require write permissions for locking and badblock ioctls MEMLOCK, MEMUNLOCK and OTPLOCK modify protection bits. Thus require write permission. Depending on the hardware MEMLOCK might even be write-once, e.g. for SPI-NOR...
