Red Hat Enterprise Linux 10: Time-of-check Time-of-use (TOCTOU) Race Condition
A flaw was found in DPDK lib/vhost vhost-crypto. The indirect-descriptor snapshot double-fetches a guest descriptor next index, allowing a malicious guest to cause an out-of-bounds access in the host backend.
- 8.2 High severity
Red Hat Enterprise Linux 10: Out-of-bounds Write
A flaw was found in DPDK lib/vhost. A guest can desynchronize virtqueue size from inflight descriptor table size, causing an out-of-bounds write in the host vhost process.

Red Hat Enterprise Linux 10: Concurrent Execution using Shared Resource with Improper Synchronization
A flaw was found in DPDK lib/vhost. A TOCTOU double-fetch of control-queue descriptors allows a heap buffer overflow with attacker-controlled content in the VDUSE control-queue handler.
- 8.6 High severity

Fast Datapath for Red Hat Enterprise Linux 10: Improper Handling of Length Parameter Inconsistency
A flaw was found in OVN (Open Virtual Network). A remote attacker, by sending crafted DHCPv6 (Dynamic Host Configuration Protocol for IPv6) SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet.
- 7.4 High severity
Fast Datapath for Red Hat Enterprise Linux 8: Out-of-bounds Read
An out-of-bounds read vulnerability was found in DPDK's Vhost library checksum offload feature. This issue enables an untrusted or compromised guest to crash the hypervisor's vSwitch by forging Virtio descriptors to cause out-of-bounds reads. This flaw allows
- 7.5 High severity
openvswitch: Uncaught Exception
