Description
In the Linux kernel, the following vulnerability has been resolved:
uaccess: fix integer overflow on access_ok()
Three architectures check the end of a user access against the
address limit without taking a possible overflow into account.
Passing a negative length or another overflow in here returns
success when it should not.
Use the most common correct implementation here, which optimizes
for a constant 'size' argument, and turns the common case into a
single comparison.
Affected configurations
• linux linux kernel (>= 3.2 < 5.15.32)
• linux linux kernel (>= 5.16 < 5.16.18)
• linux linux kernel 5.17
