Description
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.
