High (8.8) in Linux Kernel. In CISA KEV since 2022-09-15. EPSS 40% chance of exploitation in the next 30 days.
The (1) get_user and (2) put_user API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against Android devices in October and November 2013.
