Description

This security bulletin contains information about 1 vulnerability.


1) Function Call with Incorrectly Specified Arguments (CVE-ID: CVE-2026-98833)

CWE-ID: CWE-628 - Function Call with Incorrectly Specified Arguments

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to potentially cause a denial of service by triggering invalid memory access in the kernel.

The vulnerability exists due to an incorrect callback argument in __get_mtd_device() in the Linux kernel MTD core when acquiring a gluebi partition device. A local user can trigger device acquisition for a gluebi partition to potentially crash the kernel because gluebi_get_device() uses container_of() on a partition MTD object instead of the required master MTD object.
