CVE-2026-98740

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.
