CVE-2026-0962
Description
A flaw was found in Wireshark. A remote attacker could entice a user to open a specially crafted packet capture file. This action would trigger a crash in the SOME/IP-SD protocol dissector, leading to a Denial of Service (DoS) for the affected system.
Statement
This vulnerability is rated Moderate for Red Hat. An out-of-bounds write in the Wireshark SOME/IP-SD protocol dissector can lead to a denial of service. Exploitation requires user interaction, as a victim must open a specially crafted packet trace file or capture malicious network traffic. Impact is limited to systems where Wireshark is installed and actively used to process untrusted network captures.
Mitigation
To mitigate this issue, avoid opening untrusted capture files or analyzing untrusted live network traffic with Wireshark. Users should only process network data from known and trusted sources. If Wireshark is not actively used, consider removing the package to reduce the attack surface.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
