Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.26%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its path argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution.
