In the Linux kernel, the following vulnerability has been resolved:
nvmem: core: limit cell sysfs permissions to main attribute ones
The cell sysfs attribute should not provide more access to the nvmem
data than the main attribute itself.
For example if nvme_config::root_only was set, the cell attribute
would still provide read access to everybody.
Mask out permissions not available on the main attribute.
