Overview

CVE-2026-93263 is a known-severity vulnerability. It was published on September 24, 2026.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

clk: eswin: Zero-initialize stack-allocated clk_init_data

eswin_clk_register_pll() and eswin_register_clkdiv() declare a struct

clk_init_data on the stack and only initialize some of its fields

(parent_data respectively parent_hws). clk_core_populate_parent_map()

checks parent_names first and parent_data second before falling back

to parent_hws, so leftover stack garbage in the uninitialized fields

hijacks parent resolution and the clk core dereferences a bogus

pointer:

Unable to handle kernel NULL pointer dereference at virtual address 000000000000000c

How can CyberStrike help with CVE-2026-93263?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-93263 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
