Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.
