As for the description, Apple says “a memory consumption issue was addressed with improved memory handling,” and then mentions “CVE-2020-9859: unc0ver”.

@Pwn20wnd from the unc0ver team said earlier today, “iOS 13.5.1 and tvOS 13.4.6 were just released to patch the kernel vulnerability used by the #unc0ver jailbreak. Do not update your devices.”
The unc0ver team released its iOS 13.5 jailbreak last week and Apple has already patched the jailbreak. For those with jailbroken devices, they are being advised to not update to iOS 13.5.1 as that will remove the jailbreak.
