Lifecycle Timeline
1DescriptionNVD
In the Linux kernel, the following vulnerability has been resolved:
usbnet: ipheth: do not stop RX on failing RX callback
RX callbacks can fail for multiple reasons:
- Payload too short
- Payload formatted incorrecly (e.g. bad NCM framing)
- Lack of memory
None of these should cause the driver to seize up.
Make such failures non-critical and continue processing further incoming URBs.
AnalysisAI
In the Linux kernel, the following vulnerability has been resolved: usbnet: ipheth: do not stop RX on failing RX callback RX callbacks can fail for multiple reasons: * Payload too short * Payload. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
Technical ContextAI
In the Linux kernel, the following vulnerability has been resolved: usbnet: ipheth: do not stop RX on failing RX callback RX callbacks can fail for multiple reasons: * Payload too short * Payload formatted incorrecly (e.g. bad NCM framing) * Lack of memory None of these should cause the driver to seize up. Make such failures non-critical and continue processing further incoming URBs. Affected products include: Linux Linux Kernel.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Apply vendor patches when available. Implement network segmentation and monitoring as interim mitigations.
