1) Buffer overflow (CVE-ID: CVE-2025-6965)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error when processing aggregated terms. A remote attacker can pass specially crafted input to the application where the number of aggregate terms exceeds the number of columns available, trigger memory corruption and perform a denial of service (DoS) attack.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2025-4598)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists in systemd-coredump when handling process crashes. A local user who can force a SUID process to crash can replace it with a non-SUID binary to access the original's privileged process coredump and read sensitive data, such as /etc/shadow content, loaded by the original process.


3) Race condition (CVE-ID: CVE-2025-40909)

The vulnerability allows a local user to tamper with application's behavior.

The vulnerability exists due to a race condition if a directory handle is open at thread creation. A local user can exploit the race and force the application to load code or access files from unexpected location.
