kernel: stack overflow problem in Open vSwitch kernel module leading to DoS

A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result,...

lldp/openvswitch: denial of service via externally triggered memory leak

A flaw was found in multiple versions of Open vSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability...
