A NULL pointer dereference issue has been identified in the mt7915 mac fill rx vector routine of the mt76 driver in the Linux kernel. This issue occurs when the chip does not support dbdc and the hardware reports the band idx set to 1.

A use-after-free issue has been identified in the igb clean tx ring routine when the NIC is running in XDP mode. This issue can be triggered by redirecting traffic into the igb NIC and then closing the device while the traffic is flowing. The problem arises from the `igb clean tx ring` function, which is called by `igb down`, ` igb close`, and `igb xdp`.

A NULL pointer dereference vulnerability has been resolved in the Linux kernel. The issue occurred in the mt7915 get phy mode routine when adding an IBSS interface to the mt7915 driver. This vulnerability could lead to a kernel crash or potentially allow an attacker to execute arbitrary code.

The issue is related to a possible array out of bound access in the `mt7921 mcu tx rate report` function. This could potentially lead to security issues. The problem has been resolved by fixing the array out of bound issue and removing an unnecessary variable in the `mt7921 mcu tx rate report` function.
