| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.5.0-rc2+
Description
The Linux kernel contains an issue within the bpf and cpumap subsystems related to handling socket buffers (skb) during pointer ring cleanup. Specifically, the
cpu map ring cleanup() function does not properly handle skb mode, treating socket buffers within the pointer ring as XDP frames. This can lead to incorrect memory usage and warnings during XDP redirect operations, particularly when using both skb-mode and stress-mode. A premature stop of the kthread cpu map kthread run() can also contribute to this issue.Recommendations
Update to a version later than 6.5.0-rc2+ to address this issue.
