CVE-2026-80933
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: validate default EEPROM firmware size The default EEPROM firmware is parsed and copied as a full EEPROM without checking its length.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: validate default EEPROM firmware size The default EEPROM firmware is parsed and copied as a full EEPROM without checking its length. A truncated file can make the driver read beyond the firmware buffer during variant validation or the fallback copy. Reject files shorter than MT7996_EEPROM_SIZE before parsing or copying the firmware.
