CVE-2025-71156

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel had an issue where interrupts were automatically enabled upon request, potentially firing before the associated NAPI context was fully initialized. This could lead to failures as demonstrated by the provided call trace. The issue occurs because the interrupt lifecycle is not strictly coupled with the readiness of the NAPI context. The recommended solution is to use the IRQF NO AUTOEN flag when requesting interrupts to prevent auto-enablement and explicitly enable the interrupt within the NAPI initialization path, disabling it during NAPI teardown. The napi poll function and net rx action function are involved in the process.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
