CVE-2025-38422
In the Linux kernel, the following vulnerability has been resolved: net: lan743x: Modify the EEPROM and OTP size for PCI1xxxx devices Maximum OTP and EEPROM size for hearthstone PCI1xxxx devices are 8 Kb and 64 Kb respectively.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%). 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: net: lan743x: Modify the EEPROM and OTP size for PCI1xxxx devices Maximum OTP and EEPROM size for hearthstone PCI1xxxx devices are 8 Kb and 64 Kb respectively. Adjust max size definitions and return correct EEPROM length based on device. Also prevent out-of-bound read/write.
