CVE-2022-49289: Linux Kernel

High severity, CVSS 7.1. EPSS: 0.3% chance of exploitation in the next 30 days.

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 products

• Linux Linux Kernel: from 3.2, before 5.15.32 (fixed in 5.15.32); from 5.16, before 5.16.18 (fixed in 5.16.18); version 5.17 only
