NVMEM ONIE-TLV Layout Driver Infinite Loop on Unknown Type

Publication date: 2026-07-01

Last updated on: 2026-07-01

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: nvmem: layouts: onie-tlv: fix hang on unknown types The EEPROM on my board has a vendor specific entry of type 0x41. When stumbling upon that, this driver hangs in an endless loop. Fix it by keep incrementing the offset on unknown entries, so the loop will eventually stop.

Executive Summary

This vulnerability occurs in the Linux kernel's nvmem subsystem, specifically in the onie-tlv layout driver. The issue arises when the driver encounters an unknown vendor-specific entry type (0x41) in the EEPROM on a board. Instead of handling this unknown type properly, the driver enters an endless loop, causing the system to hang.

The fix involves modifying the driver to increment the offset when it encounters unknown entries, allowing the loop to eventually stop and preventing the hang.

Impact Analysis

This vulnerability can cause the Linux kernel to hang when it processes certain EEPROM data containing unknown vendor-specific entries. This hang can lead to system unresponsiveness or downtime, potentially disrupting normal operations on affected devices.
