CVE-2021-46973

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A potential use after free issue in the MHI send functionality of the Linux kernel has been resolved. The MHI ul callback may be invoked immediately after the skb is queued for transmission, leading to the callback decrementing the refcount of the associated sk and freeing the skb. To avoid this issue, the dereference of skb and the increment of the sk refcount must happen before the skb is queued.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
