Technical description
In the Linux kernel, the following vulnerability has been resolved:
EDAC/altera: Drop __init from ECC setup paths for re-probe safety
Sashiko reports:
"Does suppressing sysfs unbinding fully prevent the execution of freed __init
memory? If altr_sysmgr_regmap_lookup_by_phandle() returns -EPROBE_DEFER, the
probe is deferred until after __init memory is freed."
The a10 EDAC .setup callbacks (sdmmc, ethernet, nand, dma, usb, qspi) and
their helpers (altr_init_a10_ecc_device_type, altr_init_a10_ecc_block) were
marked __init. These run from the probe path, which may execute after init
memory is freed -- e.g. a probe deferred via -EPROBE_DEFER that only succeeds
once a late/module dependency appears, or a manual unbind/rebind. Calling
__init code then dereferences freed memory. Remove __init so these functions
remain valid at runtime.
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.

How can CyberStrike help with CVE-2026-98740?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-98740 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.
