CVE-2024-42112

  2. Vulnerabilities (CVE)
  3. CVE-2024-42112
In the Linux kernel, the following vulnerability has been resolved: net: txgbe: free isb resources at the right time When using MSI/INTx interrupt, the shared interrupts are still being handled in the device remove routine, before free IRQs. So isb memory is still read after it is freed. Thus move wx_free_isb_resources() from txgbe_close() to txgbe_remove(). And fix the improper isb free action in txgbe_open() error handling path.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: txgbe: recursos isb libres en el momento adecuado Cuando se utiliza la interrupción MSI/INTx, las interrupciones compartidas todavía se manejan en la rutina de eliminación del dispositivo, antes de las IRQ libres. Por lo tanto, la memoria isb todavía se lee después de liberarla. Por lo tanto, mueva wx_free_isb_resources() de txgbe_close() a txgbe_remove(). Y corrija la acción gratuita de isb incorrecta en la ruta de manejo de errores txgbe_open().
