CVE-2024-53082: virtio_net: Add hash_key_length check

In the Linux kernel, the following vulnerability has been resolved: virtio_net: Add hash_key_length check Add hash_key_length check in virtnet_probe() to avoid possible out of bound errors when setting/reading the hash key.

Security readout for executives and security teams

Plain-English summary

A Linux virtio_net driver flaw can cause memory access outside intended bounds when an invalid hash-key length is handled. Successful exploitation could threaten confidentiality, integrity, and availability, but the supplied evidence does not establish remote reachability, code execution, or exploitation in the wild.

Executive priority

Treat as a high-priority kernel maintenance issue on systems using virtio_net. Accelerate validation and patching where untrusted local workloads exist. Emergency incident response is not supported solely by this record because active exploitation is not established.

Technical view

virtnet_probe() lacked validation of hash_key_length before setting or reading the virtio network hash key, creating possible out-of-bounds access. The record classifies it as CWE-125 with CVSS 3.1 score 8.4 and a local, low-complexity, no-privilege, no-interaction vector. Kernel stable commits add the missing check.

Likely exposure

Exposure requires an affected Linux kernel and use of the virtio_net code path during device probing. The bundle lists versions spanning 5.18 through several fixed stable releases, but its version entries are insufficient to define every vulnerable distribution package precisely. Confirm status through the relevant Linux distributor.

Exploitation context

The CVSS vector describes a local attack path requiring neither privileges nor user interaction. CISA KEV status is false, and the supplied sources provide no evidence of active exploitation or a public exploit. Preconditions and practical impact beyond possible out-of-bounds errors are not documented in the bundle.

Researcher notes

The central issue is missing bounds validation for hash_key_length in virtnet_probe(). Multiple stable-tree commits indicate backports across kernel branches. The supplied affected-version data appears mixed and duplicated, so commit ancestry or distributor package mapping is necessary. Avoid inferring remote exploitation or arbitrary code execution from the CVSS impacts alone.

Mitigation direction

  • Install a distributor-supported kernel containing the applicable virtio_net stable fix.
  • Reboot into the updated kernel and retire vulnerable kernel packages where operationally appropriate.
  • Check Linux distributor guidance for exact package versions and required maintenance.
  • Prioritize systems using virtio_net when scheduling remediation.

Validation and detection

  • Inventory running kernel versions, not merely installed package versions.
  • Determine whether virtio_net is present and used on each potentially affected system.
  • Compare kernel packages against distributor advisories and the referenced stable fixes.
  • After updating, verify systems booted into the intended fixed kernel.
  • Review kernel logs for virtio_net faults or memory-access warnings.
