  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-56605
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create() bt_sock_alloc() allocates the sk object and attaches it to the provided sock object. On error l2cap_sock_alloc() frees the sk object, but the dangling pointer is still attached to the sock object, which may create use-after-free in other code.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Bluetooth: L2CAP: no dejar el puntero sk colgando en caso de error en l2cap_sock_create() bt_sock_alloc() asigna el objeto sk y lo adjunta al objeto sock proporcionado. En caso de error, l2cap_sock_alloc() libera el objeto sk, pero el puntero colgando sigue adjunto al objeto sock, lo que puede crear un use-after-free en otro código.
