Detailsinfo

A vulnerability, which was classified as critical, was found in zephyrproject-rtos Zephyr (Project Management Software) (affected version unknown). Affected is an unknown functionality of the component CAN Frame Handler. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. CVE summarizes:

The denial-of-service can be triggered by transmitting a carefully crafted CAN frame on the same CAN network as the vulnerable node. The frame must have a CAN ID matching an installed filter in the vulnerable node (this can easily be guessed based on CAN traffic analyses). The frame must contain the opposite RTR bit as what the filter installed in the vulnerable node contains (if the filter matches RTR frames, the frame must be a data frame or vice versa).

The weakness was released 10/31/2022 as GHSA-hx5v-j59q-c3j8. The advisory is shared for download at github.com. This vulnerability is traded as CVE-2022-2741 since 08/09/2022.
