Description

This security bulletin contains information about 8 vulnerabilities.

1) Untrusted Pointer Dereference (CVE-ID: CVE-2026-34489)

CWE-ID: CWE-822 - Untrusted Pointer Dereference

CVSSv4: 5.9 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]

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

The vulnerability exists due to insufficient validation of user-supplied input. A local attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

2) Out-of-bounds write (CVE-ID: CVE-2026-33094)

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

CVSSv4: 5.9 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local attacker to compromise vulnerable system.

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

3) Out-of-bounds write (CVE-ID: CVE-2026-40694)

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

CVSSv4: 5.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to compromise vulnerable system.

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

4) NULL pointer dereference (CVE-ID: CVE-2026-28730)

CWE-ID: CWE-476 - NULL Pointer Dereference

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

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

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

5) Heap-based buffer overflow (CVE-ID: CVE-2026-34017)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 5.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]

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

The vulnerability exists due to a boundary error. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.

6) Out-of-bounds read (CVE-ID: CVE-2026-40424)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 5.9 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N]

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

The vulnerability exists due to a boundary condition. A local attacker can trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.

7) Heap-based buffer overflow (CVE-ID: CVE-2026-63540)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

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

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

The vulnerability exists due to a boundary error. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.

8) Out-of-bounds read (CVE-ID: CVE-2026-40216)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N]

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition. A local user can trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack..
