ovn: insufficient validation of BFD packets may lead to denial of service

A flaw was found in the Open Virtual Network OVN. In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from inside unprivileged workloads, including virtual machines or containers, that can trigger a denial of service...

The vulnerability of the inflate_buffer() function in the VNC server QEMU, which allows a hacker to cause a service failure

The vulnerability of the inflatebuffer function in the VNC server QEMU is related to an incorrect exit condition, which leads to an infinite loop during buffer inflation using zlib. Exploiting this vulnerability allows a remote attacker to cause service interruptions...

kernel: Linux kernel HSR driver: Denial of Service via uninitialized value access

A flaw was found in the High-availability Seamless Redundancy HSR driver within the Linux kernel. A local user can trigger this vulnerability by sending specific Virtual Local Area Network VLAN packets to an HSR interface. This can lead to an uninitialized value being accessed, causing a Denial o...
