n the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: fix wild-memory-access in proto_unregister There's issue as follows: KASAN: maybe wild-memory-access in range [0xdead...108-0xdead...10f] CPU: 3 UID: 0 PID: 2805 Comm: rmmod Tainted: G W RIP: 0010:proto_unregister+0xee/0x400 Call Trace: <TASK> __do_sys_delete_module+0x318/0x580 do_syscall_64+0xc1/0x1d0 entry_SYSCALL_64_after_hwframe+0x77/0x7f As bnep_init() ignore bnep_sock_init()'s return value, and bnep_sock_init() will cleanup all resource. Then when remove bnep module will call bnep_sock_cleanup() to cleanup sock's resource. To solve above issue just return bnep_sock_init()'s return value in bnep_exit().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Bluetooth: bnep: corrige wild-memory-access en proto_unregister Hay un problema como el siguiente: KASAN: tal vez wild-memory-access en el rango [0xdead...108-0xdead...10f] CPU: 3 UID: 0 PID: 2805 Comm: rmmod Tainted: GW RIP: 0010:proto_unregister+0xee/0x400 Seguimiento de llamadas: __do_sys_delete_module+0x318/0x580 do_syscall_64+0xc1/0x1d0 entry_SYSCALL_64_after_hwframe+0x77/0x7f Como bnep_init() ignora el valor de retorno de bnep_sock_init(), y bnep_sock_init() limpiará Todos los recursos. Luego, cuando se elimine el módulo bnep, se llamará a bnep_sock_cleanup() para limpiar el recurso de Sock. Para resolver el problema anterior, simplemente devuelva el valor de retorno de bnep_sock_init() en bnep_exit().
