CVE-2026-98676

/// Technical description

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

iio: adc: ade9000: fix NULL pointer dereference in clkout registration

ade9000_setup_clkout() passes NULL as the register address when

registering a divider clock. During clock registration, the common

clock framework calls clk_divider_recalc_rate(), which dereferences

the address through readl(). As a result, probing an ADE9000 configured

as a clock provider with an external input clock crashes.

CLKOUT passes CLKIN through without changing its rate. Register it as

a 1:1 fixed-factor clock, which does not require register access.

This change does not affect the configuration using the internal clock,

for which the driver does not register a clock provider.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
