CVE-2024-56654

CVE-2024-56654 affects the Linux kernel Bluetooth stack. The flaw arises from using rcu_read_(un)lock inside list_for_each_entry_rcu, which is unsafe because entries dereferenced under RCU must be obtained via rcu_dereference(). The advisory states this is not legal and describes a patch that fix...
