Jul 24 ENRICHED — CVE-2026-53332 (Linux). Received CVSS 5.5 and CPE data from NVD.
Description
In the Linux kernel, the following vulnerability has been resolved:
slimbus: qcom-ngd-ctrl: Register callbacks after creating the ngd
When the remoteproc starts in parallel with the NGD driver being probed,
or the remoteproc is already up when the PDR lookup is being registered,
or in the theoretical event that we get an interrupt from the hardware,
these callbacks will operate on uninitialized data. This result in
issues to boot the affected boards.
One such example can be seen in the following fault, where
qcom_slim_ngd_ssr_pdr_notify() schedules work on the NULL ngd_up_work.

Move the enablement of interrupts, and the registration of SSR and PDR
until after the NGD device has been registered.
This could be further refined by moving initialization to the control
driver probe and by removing the platform driver model from the picture.
