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.
