| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel has a problem where it does not support struct arguments in trampoline programs for the LoongArch architecture. This can lead to a kernel oops when running BPF selftests, specifically when executing the 'tracing struct' test. The issue involves a failure in handling struct arguments, resulting in a kernel panic and potential system instability. The root cause appears to be related to the BPF (Berkeley Packet Filter) subsystem and its interaction with the LoongArch architecture. The error manifests as an RCU (Read-Copy Update) stall, indicating potential issues with memory management and synchronization. The stack trace reveals the involvement of functions like
schedule, schedule, schedule timeout, rcu gp fqs loop, and rcu gp kthread.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
