In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: prevent NULL pointer dereference in mt7925_tx_check_aggr() Move the NULL check for 'sta' before dereferencing it to prevent a possible crash.

A flaw was found in the Linux kernel's wifi subsystem, specifically within the mt76: mt7925 driver. This vulnerability arises from a missing check for a NULL pointer before it is used in the `mt7925_tx_check_aggr()` function. Exploiting this flaw could lead to a system crash, causing a Denial of Service (DoS).
