  "description": "In the Linux kernel, the following vulnerability has been resolved:  sfc: fix null pointer dereference in efx_hard_start_xmit  Trying to get the channel from the tx_queue variable here is wrong because we can only be here if tx_queue is NULL, so we shouldn\u0027t dereference it. As the above comment in the code says, this is very unlikely to happen, but it\u0027s wrong anyway so let\u0027s fix it.  I hit this issue because of a different bug that caused tx_queue to be NULL. If that happens, this is the error message that we get here:   BUG: unable to handle kernel NULL pointer dereference at 0000000000000020   [...]   RIP: 0010:efx_hard_start_xmit\u002B0x153/0x170 [sfc]",
