n the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Fix possible crash when setting up bsg fails If bsg_setup_queue() fails, the bsg_queue is assigned a non-NULL value. Consequently, in mpi3mr_bsg_exit(), the condition "if(!mrioc->bsg_queue)" will not be satisfied, preventing execution from entering bsg_remove_queue(), which could lead to the following crash: BUG: kernel NULL pointer dereference, address: 000000000000041c Call Trace: <TASK> mpi3mr_bsg_exit+0x1f/0x50 [mpi3mr] mpi3mr_remove+0x6f/0x340 [mpi3mr] pci_device_remove+0x3f/0xb0 device_release_driver_internal+0x19d/0x220 unbind_store+0xa4/0xb0 kernfs_fop_write_iter+0x11f/0x200 vfs_write+0x1fc/0x3e0 ksys_write+0x67/0xe0 do_syscall_64+0x38/0x80 entry_SYSCALL_64_after_hwframe+0x78/0xe2

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: mpi3mr: Se corrige un posible bloqueo cuando falla la configuración de bsg Si bsg_setup_queue() falla, a bsg_queue se le asigna un valor distinto de NULL. En consecuencia, en mpi3mr_bsg_exit(), la condición "if(!mrioc-&gt;bsg_queue)" no se cumplirá, lo que evitará que la ejecución ingrese a bsg_remove_queue(), lo que podría provocar el siguiente bloqueo: ERROR: desreferencia de puntero NULL del núcleo, dirección: 000000000000041c Seguimiento de llamadas: mpi3mr_bsg_exit+0x1f/0x50 [mpi3mr] mpi3mr_remove+0x6f/0x340 [mpi3mr] pci_device_remove+0x3f/0xb0 device_release_driver_internal+0x19d/0x220 unbind_store+0xa4/0xb0 kernfs_fop_write_iter+0x11f/0x200 vfs_write+0x1fc/0x3e0 ksys_write+0x67/0xe0 hacer_syscall_64+0x38/0x80 entry_SYSCALL_64_after_hwframe+0x78/0xe2
