CVE-2026-25710
HighSummary
The new privileged D-Bus helper, plasmaloginauthhelper, has multiple issues, including the ability for a compromised plasmalogin service account to chown() arbitrary files in the system.
Risk Assessment
Compromising the plasmalogin service account could lead to unauthorized modification of system files, posing a serious threat to system integrity.
Recommendation
It is recommended to monitor the plasmalogin service account and implement additional security measures to prevent its compromise.
