CVE-2013-6282 WRITEUP HIGH WRITEUP
Android get_user/put_user Exploit
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.
CVSS 8.8
CVE-2018-18021 WRITEUP HIGH WRITEUP
Linux Kernel < 4.18.12 - Unauthenticated Denial of Service and Control Flow Hijack via KVM_SET_ON_REG ioctl
arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes.
CVSS 7.1
CVE-2013-4254 WRITEUP WRITEUP
Linux Kernel < 3.10.8 - Privilege Escalation via ARM Perf Event Validation
The validate_event function in arch/arm/kernel/perf_event.c in the Linux kernel before 3.10.8 on the ARM platform allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) by adding a hardware event to an event group led by a software event.
