CVE-2023-52838 Open this link in a new tabHow to fix?
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:
fbdev: imsttfb: fix a resource leak in probe
I've re-written the error handling but the bug is that if init_imstt() fails we need to call iounmap(par->cmap_regs).
