Description OSIDB Bzimport 2024-12-27 15:05:09 UTC 
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_core: Fix not checking skb length on hci_acldata_packet

This fixes not checking if skb really contains an ACL header otherwise
the code may attempt to access some uninitilized/invalid memory past the
valid skb->data.
