Description OSIDB Bzimport 2025-07-09 11:01:54 UTC

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

atm: clip: prevent NULL deref in clip_push()

Blamed commit missed that vcc_destroy_socket() calls
clip_push() with a NULL skb.

If clip_devs is NULL, clip_push() then crashes when reading
skb->truesize.
