5.5 · MEDIUMOverview
CVE-2026-64230 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 24, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
regulator: tps65219: fix irq_data.rdev not being assigned
Commit 64a6b577490c ("regulator: tps65219: Remove debugging helper
function") removed the tps65219_get_rdev_by_name() helper along with
the irq_data.rdev assignment that depended on it. This left
irq_data.rdev uninitialized for all IRQs, causing undefined behavior
when regulator_notifier_call_chain() is called from the IRQ handler:
Internal error: Oops: 0000000096000004
pc : regulator_notifier_call_chain
lr : tps65219_regulator_irq_handler
Call trace:
regulator_notifier_call_chain
tps65219_regulator_irq_handler
handle_nested_irq
regmap_irq_thread
irq_thread_fn
irq_thread
kthread
ret_from_fork
Instead of restoring a dedicated lookup array, restructure the probe
function to combine regulator registration with IRQ registration in
the same loop. This way the rdev returned by devm_regulator_register()
is naturally available for ass
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
