fkie_cve-2025-38546

In the Linux kernel, the following vulnerability has been resolved:

atm: clip: Fix memory leak of struct clip_vcc.

ioctl(ATMARP_MKIP) allocates struct clip_vcc and set it to vcc->user_back.

The code assumes that vcc_destroy_socket() passes NULL skb to vcc->push() when the socket is close()d, and then clip_push() frees clip_vcc.

However, ioctl(ATMARPD_CTRL) sets NULL to vcc->push() in atm_init_atmarp(), resulting in memory leak.

Let's serialise two ioctl() by lock_sock() and check vcc->push() in atm_init_atmarp() to prevent memleak.
