CVE-2026-80715

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

Description An issue exists where the interface fails to go down when an AF XDP zero-copy application is killed abruptly. In this scenario, the XSK pool is torn down while NAPI (New API, a mechanism for reducing interrupt overhead) continues polling. The function igc clean rx irq zc() returns the full budget on every poll, preventing napi complete done() from clearing the NAPI STATE SCHED state. Consequently, the igc down() function calls napi synchronize() before napi disable(), causing the system to spin indefinitely while waiting for the state bit to clear.

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