CVE-2024-41005

In the Linux kernel, the following vulnerability has been resolved: netpoll: Fix race condition in netpoll_owner_active KCSAN detected a race condition in netpoll: BUG: KCSAN: data-race in net_rx_action / netpoll_send_skb write (marked) to 0xffff8881164168b0 of 4 bytes by interrupt on cpu 10: net_rx_action (./include/linux/netpoll.h:90 net/core/dev.c:6712 net/core/dev.c:6822) <snip> read to 0xffff8881164168b0 of 4 bytes by task 1 on cpu 2: netpoll_send_skb (net/core/netpoll.c:319 net/core/netpoll.c:345 net/core/netpoll.c:393) netpoll_send_udp (net/core/netpoll.c:?) <snip> value changed: 0x0000000a -> 0xffffffff This happens because netpoll_owner_active() needs to check if the current CPU is the owner of the lock, touching napi->poll_owner non atomically. The ->poll_owner field contains the current CPU holding the lock. Use an atomic read to check if the poll owner is the current CPU.

Summary
  • (es) En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: netpoll: Corrige condición de ejecución en netpoll_owner_active KCSAN detectó una condición de ejecución en netpoll: ERROR: KCSAN: data-race en net_rx_action / netpoll_send_skb escribe (marcado) en 0xffff8881164168b0 de 4 bytes por interrupción en CPU 10: net_rx_action (./include/linux/netpoll.h:90 net/core/dev.c:6712 net/core/dev.c:6822) leído en 0xffff8881164168b0 de 4 bytes por tarea 1 en la CPU 2 : netpoll_send_skb (net/core/netpoll.c:319 net/core/netpoll.c:345 net/core/netpoll.c:393) netpoll_send_udp (net/core/netpoll.c:?) valor cambiado: 0x0000000a -&gt; 0xffffffff Esto sucede porque netpoll_owner_active() necesita verificar si la CPU actual es la propietaria del bloqueo, tocando napi-&gt;poll_owner de forma no atómica. El campo -&gt;poll_owner contiene la CPU actual que mantiene el bloqueo. Utilice una lectura atómica para comprobar si el propietario de la encuesta es la CPU actual.
