Null Pointer Dereference in Linux Kernel Affecting Multiple Distributions

CVE-2023-53250

What is CVE-2023-53250?

A null pointer dereference vulnerability has been identified in the Linux kernel, specifically in the dmi-sysfs module, which can lead to kernel panic and system instability. This issue arises during memory deallocation processes due to incorrect handling of list structures, resulting in failure to properly delete uninitialized list heads. The vulnerability was addressed by adjusting error handling routines to ensure that operations on list structures are safely managed. Users are advised to update their systems to mitigate potential risks associated with this flaw.
