Name of the Vulnerable Software and Affected Versions Linux kernel versions (affected versions not specified)

Description A kernel panic issue in the MT7921 driver was resolved. The issue stemmed from accessing unallocated memory (eeprom.data) within the mt7921 mcu parse response function, potentially leading to invalid memory access. The fix avoids accessing this unallocated memory. The mt7921 mcu parse eeprom function can be eliminated, relying solely on mt7921 mcu parse response for RxD header division.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
