Description
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).
Affected configurations
• linux linux kernel (>= 5.10.0 < 5.10.36)
• linux linux kernel (>= 5.11.0 < 5.11.20)
• linux linux kernel (>= 5.12.0 < 5.12.3)
