In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: avoid use of uninit sender vars batadvtprecvack() and batadvtpstop() are only valid for tpvars in the BATADVTPSENDER role. When called with a BATADVTPRECEIVER role, it proceeds to read sender-only members that were never initialized, leading to undefined behavior. This can be triggered when a node that is currently acting as a receiver in an ongoing tpmeter session receives a malicious ACK packet. Guard against this by checking tpvars->role immediately after the lookup and bailing out if it is not BATADVTP_SENDER, before any of those members are accessed.
