It may be\nsufficient just to do \"ls /afs\" and the oops looks something like:\n\n        BUG: kernel NULL pointer dereference, address: 0000000000000020\n        ...\n        RIP: 0010:afs_getattr+0x8b/0x14b\n        ...\n        Call Trace:\n         <TASK>\n         vfs_statx+0x79/0xf5\n         vfs_fstatat+0x49/0x62"},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: afs: Fix dynamic root getattr El parche reciente para hacer que afs_getattr consulte al servidor no tuvo en cuenta los pseudoinodos empleados por el superbloque afs de tipo raíz dinámico que no tienen un volumen o un servidor al que acceder, y por lo tanto ocurre un error si se agrega una estadística a dicho directorio. Arregle esto verificando si el puntero vnode-&gt;volume realmente apunta a algún lugar antes de seguirlo en afs_getattr(). Esto se puede probar agregando una estadística a un directorio en /afs.
