CVE-2026-43260

In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Fix RSS context delete logic

We need to free the corresponding RSS context VNIC

in FW everytime an RSS context is deleted in driver.

Commit 667ac333dbb7 added a check to delete the VNIC

in FW only when netif_running() is true to help delete

RSS contexts with interface down.

Having that condition will make the driver leak VNICs

in FW whenever close() happens with active RSS contexts.

On the subsequent open(), as part of RSS context restoration,

we will end up trying to create extra VNICs for which we

did not make any reservation. FW can fail this request,

thereby making us lose active RSS contexts.

Suppose an RSS context is deleted already and we try to

process a delete request again, then the HWRM functions

will check for validity of the request and they simply

return if the resource is already freed. So, even for

delete-when-down cases, netif_running() check is not

necessary.

Remove the netif_running() condition check when deleting

an RSS context.
