csrf-magic.php crash report

[e-1-1]

Hi everyone,
After leaving the management webpage on a 2.4.5-RELEASE box for several hours, I got the following crash report message:

Crash report begins.  Anonymous machine information:

FreeBSD 11.3-STABLE #236 21cbb70bbd1(RELENG_2_4_5): Tue Mar 24 15:26:53 [timezone] 2020     root@buildbot1-nyi.netgate.com:/build/ce-crossbuild-245/obj/amd64/YNx4Qq3j/build/ce-crossbuild-245/sources/FreeBSD-src/sys/pfSense

Crash report details:

No FreeBSD crash data found.

Maybe that $buffer argument is at fault here.
Not sure if this warrants a bug report.
