In the Linux kernel, the following vulnerability has been resolved:
gve: defer interrupt enabling until NAPI registration
Currently, interrupts are automatically enabled immediately upon request. This allows interrupt to fire before the associated NAPI context is fully initialized and cause failures like below:
[ 0.946369] Call Trace: [ 0.946369] <IRQ> [ 0.946369] __napi_poll+0x2a/0x1e0 [ 0.946369] net_rx_action+0x2f9/0x3f0 [ 0.946369] handle_softirqs+0xd6/0x2c0 [ 0.946369] ? handle_edge_irq+0xc1/0x1b0 [ 0.946369] __irq_exit_rcu+0xc3/0xe0 [ 0.946369] common_interrupt+0x81/0xa0 [ 0.946369] </IRQ> [ 0.946369] <TASK> [ 0.946369] asm_common_interrupt+0x22/0x40 [ 0.946369] RIP: 0010:pv_native_safe_halt+0xb/0x10
Use the `IRQF_NO_AUTOEN` flag when requesting interrupts to prevent auto enablement and explicitly enable the interrupt in NAPI initialization path (and disable it during NAPI teardown).
This ensures that interrupt lifecycle is strictly coupled with readiness of NAPI context.
