CVE-2024-50234

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlegacy: Clear stale interrupts before resuming device iwl4965 fails upon resume from hibernation on my laptop. The reason seems to be a stale interrupt which isn't being cleared out before interrupts are enabled. We end up with a race beween the resume trying to bring things back up, and the restart work (queued form the interrupt handler) trying to bring things down. Eventually the whole thing blows up. Fix the problem by clearing out any stale interrupts before interrupts get enabled during resume. Here's a debug log of the indicent: [ 12.042589] ieee80211 phy0: il_isr ISR inta 0x00000080, enabled 0xaa00008b, fh 0x00000000 [ 12.042625] ieee80211 phy0: il4965_irq_tasklet inta 0x00000080, enabled 0x00000000, fh 0x00000000 [ 12.042651] iwl4965 0000:10:00.0: RF_KILL bit toggled to enable radio.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: iwlegacy: Borrar interrupciones obsoletas antes de reanudar el dispositivo iwl4965 falla al reanudar desde la hibernación en mi computadora portátil. La razón parece ser una interrupción obsoleta que no se borra antes de que se habiliten las interrupciones. Terminamos con una ejecución entre la reanudación que intenta hacer que las cosas vuelvan a funcionar y el trabajo de reinicio (en cola desde el controlador de interrupciones) que intenta hacer que las cosas se detengan. Finalmente, todo explota. Solucione el problema borrando todas las interrupciones obsoletas antes de que las interrupciones se habiliten durante la reanudación. Aquí hay un registro de depuración del incidente: [ 12.042589] ieee80211 phy0: il_isr ISR inta 0x00000080, habilitado 0xaa00008b, fh 0x00000000 [ 12.042625] ieee80211 phy0: il4965_irq_tasklet inta 0x00000080, habilitado 0x00000000, fh 0x00000000 [ 12.042651] iwl4965 0000:10:00.0: bit RF_KILL alternado para habilitar la radio.
