Description OSIDB Bzimport 2026-08-28 07:42:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

mtd: maps: vmu-flash: fix NULL pointer dereference in initialization

The mtd_info contains a struct device, which must be linked to its
parent. Without this, the initialization of the MTD fails with a NULL
pointer dereference.
