CVE-2022-48939

Summary

CVE-2022-48939 is a vulnerability in the Linux kernel affecting various products that utilize BPF (Berkeley Packet Filter) batch operations, which can lead to soft lockups due to tasks being blocked for extended periods. The issue arises from the lack of schedule points within batch operations that process large amounts of data, leading to potential system hangs. Remediation involves applying patches that introduce necessary schedule points, which are currently being developed in the Linux kernel's next tree. The vulnerability has a low severity rating with an exploitability score of 1.8 and requires low privileges to exploit, but it poses risks related to system availability rather than confidentiality or integrity. Organizations are advised to monitor for updates and apply patches promptly to mitigate potential impacts on system performance.
