| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.0
Description
The issue is related to the Linux kernel's bpf (Berkeley Packet Filter) functionality. Specifically, it involves the
bpf map {lookup,update,delete} elem() helpers, which are used for manipulating bpf maps. These helpers are available for sleepable bpf programs and require a corresponding lock assertion to prevent warnings when a sleepable bpf program manipulates a bpf map under interpreter mode. The warning is reported when the rcu read lock trace held() check is not performed before calling the bpf map helpers.Recommendations
To resolve the issue, update the Linux kernel to a version that includes the fix for this vulnerability.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
