Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (9.08%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service).
