Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains an issue where
cls bpf classify() can modify tc skb cb(skb)->drop reason, leading to a warning within sk skb reason drop(). This occurs due to an incorrect interaction between the tc skb cb structure, introduced by commit ec624fe740b4, and BPF data handling introduced by commit db58ba459202. The drop reason field was added subsequently. The bpf prog run data pointers() helper has been added to address this by saving and restoring the net sched storage, which conflicts with BPF data meta and data end.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
