dpdk: DoS when a Vhost header crosses more than two descriptors and exhausts all mbufs

A permissive list of allowed inputs flaw was found in DPDK. This issue allows a remote attacker to cause a denial of service triggered by sending a crafted Vhost header to DPDK...

hw: cpu: incomplete clean-up of multi-core shared buffers (aka SBDR)

A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel® Processors may allow an authenticated user to enable information disclosure via local access...

kernel: veth: ensure skb entering GRO are not cloned.

In the Linux kernel, the following vulnerability has been resolved: veth: ensure skb entering GRO are not cloned. After commit d3256efd8e8b "veth: allow enabling NAPI even without XDP", if GRO is enabled on a veth device and TSO is disabled on the peer device, TCP skbs will go through the NAPI...

kernel: dma-buf/dma-resv: Stop leaking on krealloc() failure

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: Stop leaking on krealloc failure Currently dmaresvgetfences will leak the previously allocated array if the fence iteration got restarted and the kreallocarray fails. Free the old array by hand, and make sure we...

kernel: media: stk1160: If start stream fails, return buffers with VB2_BUF_STATE_QUEUED

In the Linux kernel, the following vulnerability has been resolved: media: stk1160: If start stream fails, return buffers with VB2BUFSTATEQUEUED If the callback 'startstreaming' fails, then all queued buffers in the driver should be returned with state 'VB2BUFSTATEQUEUED'. Currently, they are...

kernel: bpf, cpumap: Handle skb as well when clean up ptr_ring

An incorrect object type handling flaw was found in the Linux kernel's BPF cpumap implementation in the cleanup path. A local user can trigger this issue by running XDP redirect operations in SKB mode with the cpumap, causing the cleanup code to incorrectly treat socket buffers as XDP frames when...
