Description

This security bulletin contains information about 4 vulnerabilities.


1) Deserialization of Untrusted Data (CVE-ID: CVE-2025-33255)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local privileged user to execute arbitrary code, cause a denial of service, tamper with data, or disclose sensitive information.

The vulnerability exists due to unsafe deserialization in MPI server when processing serialized data. A local privileged user can supply crafted serialized input to execute arbitrary code, cause a denial of service, tamper with data, or disclose sensitive information.


2) Deserialization of Untrusted Data (CVE-ID: CVE-2026-24163)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local privileged user to execute arbitrary code, cause a denial of service, tamper with data, or disclose sensitive information.

The vulnerability exists due to unsafe deserialization in RPC testing when processing serialized data. A local privileged user can supply crafted serialized input to execute arbitrary code, cause a denial of service, tamper with data, or disclose sensitive information.


3) Deserialization of Untrusted Data (CVE-ID: CVE-2026-24142)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary code, tamper with data, or disclose sensitive information.

The vulnerability exists due to unsafe deserialization in serialized handle processing when handling an unsafe serialized handle. A local user can provide a crafted serialized handle to execute arbitrary code, tamper with data, or disclose sensitive information.


4) Unchecked Return Value to NULL Pointer Dereference (CVE-ID: CVE-2026-24160)

CWE-ID: CWE-690 - Unchecked Return Value to NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to an unchecked return value leading to a null pointer dereference in TensorRT-LLM when processing input. A remote attacker can trigger the null pointer dereference to cause a denial of service.

User interaction is required.
