Linux Kernel Device Management Vulnerability in Gluebi Partitions

CVE-2026-98833

What is CVE-2026-98833?

A vulnerability in the Linux kernel affects the management of Memory Technology Device (MTD) within Gluebi partitions. The issue arises when the function __get_mtd_device() retrieves the master's _get_device() callback using a partition instead of the master MTD, which creates instability in handling gluebi partitions. To rectify this, the master MTD needs to be passed correctly to the _get_device() function, ensuring seamless operation and device integrity. This vulnerability poses risks to system performance and reliability if left unaddressed.
