Name of the Vulnerable Software and Affected Versions Linux kernel versions up to 6.6.26/6.8.5

Description The issue is related to a null pointer dereference in the mediatek ctx list within the 'vpu dec ipi handler' function. This occurs when the ctx list has been deleted due to an unexpected behavior on the SCP IP block, leading to a kernel panic and potentially allowing privilege escalation. The vulnerability affects local networks.

Recommendations To resolve the issue, update the Linux kernel to a version later than 6.6.26/6.8.5. As a temporary workaround, consider disabling the 'vpu dec ipi handler' function until a patch is available.
