UBUNTU-CVE-2024-58069: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: Who is exposed to this issue?

Systems using one of the listed Ubuntu kernel packages may be exposed if they use the PCF85063 RTC driver's NVMEM interface. The out-of-bounds write is triggered when an NVMEM client requests a buffer smaller than 4 bytes.

Q: What level of access does an attacker need?

The severity vector indicates local access and low privileges are required. No user interaction is required.

Q: How can I assess whether a system is affected?

Check whether the system is running a listed Ubuntu kernel package and uses the PCF85063 RTC NVMEM interface. The relevant condition is an NVMEM read request with a buffer size of fewer than 4 bytes.

Published Mar 6, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved: rtc: pcf85063: fix potential OOB write in PCF85063 NVMEM read The nvmem interface supports variable buffer sizes, while the regmap interface operates with fixed-size storage. If an nvmem client uses a buffer size less than 4 bytes, regmapread will write out of bounds as it expects the buffer to point at an unsigned int. Fix this by using an intermediary unsigned int to hold the value.

Frequently Asked Questions

Who is exposed to this issue?

Systems using one of the listed Ubuntu kernel packages may be exposed if they use the PCF85063 RTC driver's NVMEM interface. The out-of-bounds write is triggered when an NVMEM client requests a buffer smaller than 4 bytes.

What level of access does an attacker need?

The severity vector indicates local access and low privileges are required. No user interaction is required.

How can I assess whether a system is affected?

Check whether the system is running a listed Ubuntu kernel package and uses the PCF85063 RTC NVMEM interface. The relevant condition is an NVMEM read request with a buffer size of fewer than 4 bytes.
