CVE-2024-50138

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.
