Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: soc: mediatek: mtk-svs: Enable the IRQ later If the system does not come from reset (like when is booted via kexec()), the peripheral might triger an IRQ before the data structures are initialised. [ 0.227710] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000f08 [ 0.227913] Call trace: [ 0.227918] svs_isr+0x8c/0x538

Executive Summary

This vulnerability occurs in the Linux kernel's Mediatek mtk-svs driver. If the system is booted using kexec() instead of a full reset, a peripheral device might trigger an interrupt request (IRQ) before the necessary data structures are initialized, potentially causing a kernel NULL pointer dereference and system instability or crash.

Impact Analysis

This vulnerability can cause the system to crash or become unstable due to a kernel NULL pointer dereference triggered by an IRQ occurring before initialization. This may lead to denial of service or unexpected behavior in systems using the affected Mediatek mtk-svs driver, especially when booted via kexec().
