Threats tagged 'ghsa-9fhg-rrvj-mjc8'

A vulnerability in the Linux kernel's batman-adv module was resolved involving non-atomic updates of MAC addresses. The issue allowed a parallel reader to observe partially updated MAC addresses, potentially causing network issues such as ARP cache poisoning. The fix involved using atomic64_t to ensure atomic updates of the 48-bit MAC address, preventing readers from seeing mixed old and new values.
