Description

rtc: pcf85063: fix potential OOB write in PCF85063 NVMEM read

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, regmap_read 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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
