Search: CVE-2024-56770

CVE-2024-56770 is a vulnerability in the Linux kernel's netem queuing discipline where the packet queue length ('qlen') does not correctly account for backlog updates from child qdiscs. This causes 'qlen' to inaccurately reflect the number of packets, potentially leading to the netem qdisc stopping packet acceptance prematurely, effectively locking the network interface. The issue is fixed in several Linux kernel versions starting from 4.4.0-1143.149 and others. The vulnerability has a medium severity with an impact on availability but no confidentiality or integrity loss.
