CVE-2026-25263
Description
A flaw was found in the Linux kernel. A local user can exploit this vulnerability by submitting an input/output control (IOCTL) request with invalid parameters from user space. This improper handling triggers memory corruption, which may lead to privilege escalation or a denial of service (DoS).
Statement
This vulnerability is rated as having a Moderate impact because exploitation is constrained to local users with access to character device nodes, precluding remote exploitation. The issue resides in kernel camera drivers specifically targeting Qualcomm Snapdragon system-on-chip platforms, which are not packaged or supported within Red Hat Enterprise Linux. Consequently, standard Red Hat kernel deployments do not expose this interface and are not affected under default configurations.
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.
