CVE-2024-26825

  3. CVE-2024-26825
In the Linux kernel, the following vulnerability has been resolved: nfc: nci: free rx_data_reassembly skb on NCI device cleanup rx_data_reassembly skb is stored during NCI data exchange for processing fragmented packets. It is dropped only when the last fragment is processed or when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received. However, the NCI device may be deallocated before that which leads to skb leak. As by design the rx_data_reassembly skb is bound to the NCI device and nothing prevents the device to be freed before the skb is processed in some way and cleaned, free it on the NCI device cleanup. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfc: nci: rx_data_reassembly skb gratuito en la limpieza del dispositivo NCI rx_data_reassembly skb se almacena durante el intercambio de datos NCI para procesar paquetes fragmentados. Se elimina solo cuando se procesa el último fragmento o cuando se recibe un paquete NTF con el código de operación NCI_OP_RF_DEACTIVATE_NTF. Sin embargo, el dispositivo NCI puede desasignarse antes de lo que provoca una fuga de skb. Como por diseño el skb rx_data_reassembly está vinculado al dispositivo NCI y nada impide que el dispositivo se libere antes de que el skb se procese y limpie de alguna manera, libérelo en la limpieza del dispositivo NCI. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con Syzkaller.
