Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会开源的一个操作系统内核。 Linux kernel 5.8版本存在安全漏洞，该漏洞源于mt7915_mcu_get_eeprom()将固定的EFUSE块复制到驱动缓冲区时，未检查MCU响应中由设备控制的EEPROM地址是否超出缓冲区大小，可能导致16字节越界写入。

Vulnerability Title
wifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy mt7915_mcu_get_eeprom() copies a fixed EFUSE block into the driver's dev->mt76.eeprom.data buffer at the offset reported by the MCU response (res->addr, a device-controlled __le32) without checking it against the buffer size. A malicious or malfunctioning device can report an arbitrary address and drive a 16-byte out-of-bounds write past eeprom.data. Reject a response whose address would place the copy outside eeprom.data before deriving the destination pointer. Devices that echo the requested in-bounds offset are unaffected.
