There is no fixed version for RHEL:7 kernel-rt.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt package and not the kernel-rt package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
i2c: cadence: fix reference leak when pm_runtime_get_sync fails
The PM reference count is not expected to be incremented on return in functions cdns_i2c_master_xfer and cdns_reg_slave.
However, pm_runtime_get_sync will increment pm usage counter even failed. Forgetting to putting operation will result in a reference leak here.
Replace it with pm_runtime_resume_and_get to keep usage counter balanced.
