Cross site scripting

The Linux kernel allows userspace processes to enable mitigations by calling prctl with PRSETSPECULATIONCTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to...

CVE-2023-1998

CVE-2023-1998 affects the Linux kernel. Root cause: when using legacy IBRS, the IBRS bit is cleared on returning to userspace, disabling implicit STIBP and leaving some spectre-BTI protections ineffective; attackers on a local machine could exploit cross-thread branch target injection despite mit...

CVE-2017-11063

In Android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, as a result of a race condition between two userspace processes that interact with the driver concurrently, a null pointer dereference can potentially occur...

Hardware timer context is not properly context switched on ARM

ISSUE DESCRIPTION When running on an ARM platform Xen was not context switching the CNTKCTLEL1 register, which is used by the guest kernel to control access by userspace processes to the hardware timers. This meant that any guest can reconfigure these settings for the entire system. IMPACT A...
