CVE-2026-119194 is a high-severity vulnerability in the pyasn1 library used by Glances, where schemaless decoding of BER, CER, or DER data with many distinct long tag IDs causes quadratic CPU usage. This can lead to excessive CPU consumption and reduced service availability when processing attacker-controlled inputs. The issue arises from inefficient handling of tag sets during decoding. Fixed versions 3.1.6.2 and 4.3.3_1 address this problem.
