CVE-2025-38546

Description

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 tovcc->user_back.The code assumes that vcc_destroy_socket() passes null skbto vcc->push() when the socket is close()d, and then clip_push()frees clip_vcc.However, ioctl(ATMARPD_CTRL) sets null to vcc->push() inatm_init_atmarp(), resulting in memory leak.Lets serialise two ioctl() by lock_sock() and check vcc->push()in atm_init_atmarp() to prevent memleak.
