DEBIAN-CVE-2015-3291

arch/x86/entry/entry64.S in the Linux kernel before 4.1.6 on the x8664 platform does not properly determine when nested NMI processing is occurring, which allows local users to cause a denial of service skipped NMI by modifying the rsp register, issuing a syscall instruction, and triggering an NM...

QEMU - Programmable Interrupt Timer Controller Heap Overflow

Source: https://code.google.com/p/google-security-research/issues/detail?id=419c4 The programmable interrupt timer PIT controller in QEMU does not correctly validate the channel number when performing IO writes to the device controller, allowing both an information disclosure and heap-overflow...

PT-2015-6138 · Linux +3 · Linux Kernel +3

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.1.6 Description: The issue allows local users to gain privileges by triggering an NMI within a certain instruction window due to improper reliance on espfix64 during nested NMI processing in arch/x86/entry/ent...

FreeBSD : xen-tools -- PCI MSI mask bits inadvertently exposed to guests (4db8a0f4-27e9-11e5-a4a5-002590263bf5)

The Xen Project reports : The mask bits optionally available in the PCI MSI capability structure are used by the hypervisor to occasionally suppress interrupt delivery. Unprivileged guests were, however, nevertheless allowed direct control of these bits. Interrupts may be observed by Xen at...

FreeBSD : xen-tools -- Potential unintended writes to host MSI message data field via qemu (af38cfec-27e7-11e5-a4a5-002590263bf5)

The Xen Project reports : Logic is in place to avoid writes to certain host config space fields when the guest must nevertheless be able to access their virtual counterparts. A bug in how this logic deals with accesses spanning multiple fields allows the guest to write to the host MSI message dat...

kernel: int80 fork from 64-bit tasks mishandling

A flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system...
