Description SMASH SMASH 2024-02-29 10:07:21 UTC 
In the Linux kernel, the following vulnerability has been resolved:

sfc: farch: fix TX queue lookup in TX flush done handling

We're starting from a TXQ instance number ('qid'), not a TXQ type, so
 efx_get_tx_queue() is inappropriate (and could return NULL, leading
 to panics).
