Описание
A vulnerability was found in kronosnet's (version <=1.34) cryptographic configuration management. The framework does not correctly zero-out or wipe sensitive memory segments after executing changes to its cryptographic configuration. This omission leaves raw encryption keys resident in memory after the associated structures are freed. A local attacker capable of leveraging memory disclosure techniques could exploit this flaw to retrieve the active encryption key, allowing them to decrypt cluster network communications or inject malicious packets to cause severe high-availability cluster instability.
Отчет
Red Hat Product Security rates this flaw's impact as Moderate. While kronosnet is a critical core networking component within the Red Hat Enterprise Linux High Availability (RHEL HA) ecosystem, exploiting this vulnerability requires a high degree of complexity. An attacker must already possess local access to the host machine and successfully pair this flaw with a distinct memory disclosure mechanism to extract the key fragments post-free().
