Kbi058 Patched: ((new))

In enterprise environments and modern operating systems, deployment identifiers containing "1058" frequently point to a specific, disruptive state: .

The "058" designation likely refers to an internal bug tracking ID from a major distribution (possibly SUSE or Red Hat) before the patch was upstreamed. What made KBI058 particularly insidious was its reproducibility window. It could only be triggered by a perfect storm: an NVMe drive under synchronous write pressure, a specific CPU microsleep state (C6), and a kernel compiled with CONFIG_PREEMPT_VOLUNTARY. For most users, the system ran flawlessly for weeks. Then, without warning, a database page would contain nulls where transaction logs should be, or a configuration file would become binary garbage. Forensic analysis would show no hardware errors—the RAM and SSD passed every diagnostic. The ghost was in the kernel. kbi058 patched

To ensure your system is no longer vulnerable to KBI058, verify the following: Forensic analysis would show no hardware errors—the RAM

Specifically, the vulnerability allowed an attacker to manipulate the size or content of a data structure in such a way that the kernel would write past the intended boundary of a stack variable. More critically, in scenarios where the write operation failed or was incomplete, the kernel would proceed to "copy out" the contents of the stack buffer back to user space. Because this buffer was often uninitialized (not zeroed out), this action would copy sensitive kernel stack data—such as pointers to other kernel objects, authentication tokens, or random kernel addresses—into user-accessible memory.
