Linux · Linux Kernel · CVE-2021-46949
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The issue is related to the TX queue lookup in TX flush done handling in the Linux kernel. Specifically, the problem arises because the code starts from a TXQ instance number ('qid'), not a TXQ type, making the efx get tx queue() function inappropriate and potentially leading to NULL returns and panics.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
