Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the Linux kernel's BPF (Berkeley Packet Filter) subsystem, where a vulnerability in the
may update sockmap() function allows for insufficient permission checks. This can lead to a locking rule violation when a BPF program attached to a tracepoint performs a map delete on a sockmap/sockhash. The vulnerability can be exploited to impact the integrity of protected information. The Linux kernel has resolved this issue by extending the existing verifier allowed-program-type check for updating sockmap/sockhash to also cover deleting from a map, allowing only BPF programs that were previously allowed to update sockmap/sockhash to delete from these map types.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
