Quick assessment

Affected
Linux Linux
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.

在 Linux 内核中，已修复以下漏洞： spi: 在 spi_get_device_match_data() 中为 spi_get_device_id() 添加空指针检查 防止当 spi_get_device_id() 返回 NULL 时发生空指针解引用。这种情况在使用 driver_override 且未匹配到对应的 SPI ID 条目时可能出现。
