Man-in-the-Middle (MitM)

The Network Time Protocol NTP is used to synchronize a computer's time with another referenced time source. It was found that because NTP's access control was based on a source IP address, an attacker could bypass source IP restrictions and send malicious control and configuration packets by...

kernel: TLB flush happens too late on mremap

Since Linux kernel version 3.2, the mremap syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate removes entries from the pagetables of a task that is in the middle of mremap, a stale TLB entry can remain for a short time that permits access to a physical pag...

The vulnerability of the Network Address Translation implementation in the Cisco IOS operating system allows a hacker to induce a service failure.

The vulnerability of the Network Address Translation 64 NAT64 implementation in Cisco IOS operating systems exists due to errors in the processing of IPv4 packets. Exploiting this vulnerability can allow a remote attacker to cause a system to stop responding or restart the device, resulting in...

The vulnerability of Xen hypervisors arises from insufficient data processing during the transfer of an address to the TLB reset code, allowing a malicious actor to trigger a service failure.

The vulnerability of Xen hypervisors is related to an error in the address transfer during the TLB flush code. Exploiting this vulnerability can allow an attacker to cause a service failure...

The vulnerability of Xen hypervisors, related to errors in clearing the Translation Lookaside Table (TLB) buffer, allows attackers to enhance their privileges.

The vulnerability of Xen hypervisors is related to an erroneous TLB write-after-IOMMU mapping. Exploiting this vulnerability can allow attackers to enhance their privileges...

Splitting atoms in XNU

Posted by Ian Beer, Google Project Zero TL;DR A locking bug in the XNU virtual memory subsystem allowed violation of the preconditions required for the correctness of an optimized virtual memory operation.
