CVE-2024-42072
Linux
CVE-2024-42072 is a vulnerability in the Linux kernel's Berkeley Packet Filter (BPF) component related to handling negative offsets in 'may_goto' instructions. This BPF vulnerability can lead to incorrect patching and potential infinite loop scenarios within the kernel verifier. Although CVSS scores it at 7.8, SOCRadar's Vulnerability Risk Score (SVRS) is 70, indicating a moderate risk. The improper handling of negative offsets in 'may_goto' could be exploited, although mitigation complexities are expected. The flaw stems from issues in how the kernel patches and verifies BPF programs using 'may_goto' with negative offsets, creating opportunities for unexpected behavior. Addressing CVE-2024-42072 is crucial to maintain the stability and security of systems relying on the Linux kernel, especially given the widespread use of BPF in networking and tracing. The vulnerability highlights the importance of rigorous verification processes in kernel components.
