Short explanation
A vulnerability in the Linux kernel mtd subsystem, designated CVE-2026-98833, occurs because __get_mtd_device() calls the master's _get_device() callback with mtd, which may be a partition.
This breaks gluebi partitions because gluebi_get_device() relies on container_of() and therefore requires the master MTD.
What should be done?
- Follow vendor advisories and updates
- Ensure _get_device() is called with the master MTD
Chain of evidence and sources
CVE-2026-98833, __get_mtd_device() fonksiyonunun master yerine bölüm geçirebilmesinden kaynaklanır.
Bu durum gluebi bölümlerini etkilemekte ve master MTD gerektiren gluebi_get_device() fonksiyonunu bozmaktadır.
Show the technical text from the sources
In the Linux kernel, the following vulnerability has been resolved: mtd: core: call _get_device() with the master MTD __get_mtd_device() calls the master's _get_device() callback with mtd, which may be a partition. __put_mtd_device() passes the master. This breaks gluebi partitions because gluebi_get_device() uses container_of() and therefore requires the master MTD. Pass the master to _get_device(), matching _put_device().
