CVE-2023-52475

  2. Vulnerabilities (CVE)
  3. CVE-2023-52475
In the Linux kernel, the following vulnerability has been resolved: Input: powermate - fix use-after-free in powermate_config_complete syzbot has found a use-after-free bug [1] in the powermate driver. This happens when the device is disconnected, which leads to a memory free from the powermate_device struct. When an asynchronous control message completes after the kfree and its callback is invoked, the lock does not exist anymore and hence the bug. Use usb_kill_urb() on pm->config to cancel any in-progress requests upon device disconnection. [1] https://syzkaller.appspot.com/bug?extid=0434ac83f907a1dbdd1e

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Entrada: powermate - corrige el use-after-free en powermate_config_complete syzbot ha encontrado un error de use-after-free [1] en el controlador powermate. Esto sucede cuando el dispositivo está desconectado, lo que genera una memoria libre de la estructura powermate_device. Cuando se completa un mensaje de control asincrónico después de que se invoca kfree y su devolución de llamada, el bloqueo ya no existe y de ahí el error. Utilice usb_kill_urb() en pm->config para cancelar cualquier solicitud en curso al desconectar el dispositivo. [1] https://syzkaller.appspot.com/bug?extid=0434ac83f907a1dbdd1e
