| Vector | 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 (affected versions not specified)
Description:
The issue arises from the function
bpf ringbuf reserve being invoked from a tracepoint, which disables preemption. Using spinlock t in this context can lead to a "sleep in atomic" warning in the RT variant. This is illustrated by an example where a "sleeping function called from invalid context" error occurs. The error is caused by the use of spinlock t instead of raw spinlock t in the bpf ringbuf reserve function.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
