✅ Remediation

For more information visit https://access.redhat.com/errata/RHSA-2026:68696 Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Workaround: There is no complete mitigation for this vulnerability. The following measures can reduce risk: 1. If using libaom as a standalone encoder library, avoid setting g_lag_in_frames to values >= 1 when processing untrusted input, or validate all encoder configuration parameters before passing them to the libaom API. 2. For Firefox and Thunderbird, ensure browsers are updated to versions that include the patched libaom (v3.14.0 or later). 3. For standalone libaom deployments (RHEL-AI, Hummingbird), restrict access to the encoding service to trusted clients only. 4. Apply network-level access controls to limit who can submit video for encoding. Workaround: There is no complete mitigation for this vulnerability. The following measures can reduce risk: 1. If using libaom as a standalone encoder library with SVC enabled, validate that spatial_layer_id and temporal_layer_id values are within the configured range [0, configured_layers) before calling aom_codec_control with AV1E_SET_SVC_LAYER_ID. 2. Restrict access to encoding services to trusted clients only. Do not expose libaom SVC encoder configuration to untrusted input. 3. For Firefox and Thunderbird, ensure browsers are updated to versions that include the patched libaom (v3.14.0 or later). 4. Deploy encoding services with ASLR, stack canaries, and other exploit mitigation technologies enabled. Workaround: There is no complete mitigation for this vulnerability. The following measures can reduce risk: 1. If using libaom as a standalone encoder library with SVC enabled, validate that spatial_layer_id does not exceed the number of configured spatial layers before calling aom_codec_control with AV1E_SET_SVC_LAYER_ID. 2. Restrict access to encoding services to trusted clients only. 3. For Firefox and Thunderbird, ensure browsers are updated to versions that include the patched libaom (v3.14.0 or later). 4. Monitor encoding service processes for unexpected crashes (segfaults) that may indicate exploitation attempts. Workaround: There is no complete mitigation for this vulnerability. The following measures can reduce risk: 1. If using libaom as a standalone encoder in a fork-based service, validate all SVC layer parameters (spatial_layer_id, temporal_layer_id) against configured bounds before passing them to the encoder API. 2. Avoid fork-based architectures for encoding services that accept untrusted input. Use thread-based or container-isolated workers instead, which prevent crash oracle attacks. 3. Restrict access to encoding services to trusted clients only. Do not expose SVC encoder configuration or frame submission to untrusted network input. 4. For Firefox and Thunderbird, ensure browsers are updated to versions that include the patched libaom (v3.14.0 or later). 5. Enable all available exploit mitigations (ASLR, PIE, stack canaries, CFI) on encoding service binaries.
