Description

This security bulletin contains information about 7 vulnerabilities.


1) Improper Certificate Validation (CVE-ID: CVE-2026-92868)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to improper certificate validation. A remote attacker can cause client certificate authentication bypass.


2) Out-of-bounds write (CVE-ID: CVE-2026-92867)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote user can trigger an out-of-bounds write and execute arbitrary code on the target system.


3) Out-of-bounds write (CVE-ID: CVE-2026-92869)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote user can trigger an out-of-bounds write and perform a denial of service (DoS) attack.


4) Stack-based buffer overflow (CVE-ID: CVE-2026-92870)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a boundary error. A remote unauthenticated attacker can trigger stack-based buffer overflow and cause a denial of service condition on the target system.


5) NULL pointer dereference (CVE-ID: CVE-2026-92871)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


6) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2026-92872)

CWE-ID: CWE-532 - Information Exposure Through Log Files

CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to software stores sensitive information into log files. A remote user can read the log files and gain access to sensitive data.


7) Incorrect Implementation of Authentication Algorithm (CVE-ID: CVE-2026-92873)

CWE-ID: CWE-303 - Incorrect Implementation of Authentication Algorithm

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to incorrect implementation of authentication algorithm. A remote attacker can promote an arbitrary watchdog node to the leader node.
