openvswitch: External triggered memory leak in Open vSwitch while processing fragmented packets

A memory leak was found in Open vSwitch OVS during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments...

The method PVRSRVBridgeTLDiscoverStreams allocates puiStreamsInt on the heap, fills the contents of the buffer via TLServerDiscoverStreamsKM, and then copies the buffer to userspace. The method TLServerDiscoverStreamsKM may fail for several reasons including invalid sizes. If this method fails th...

A vulnerability was found in the Linux kernel's eBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. This flaws affects kernel versions < v5.16-rc6
