Technical description

In the Linux kernel, the following vulnerability has been resolved:

clk: rs9: Fix suspend/resume

Disabling the cache in commit 2ff4ba9e3702 ("clk: rs9: Fix I2C accessors")

without removing cache synchronization in resume path results in a

kernel panic as map->cache_ops is unset, due to REGCACHE_NONE.

Enable flat cache again to support resume again. num_reg_defaults_raw

is necessary to read the cache defaults from hardware. Some registers

are strapped in hardware and cannot be provided in software.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
