AI-suggested
A fix has been implemented in the Linux kernel to address this vulnerability by correcting the handling of the "STACKTRACE" histogram key fields. Users should update to the patched kernel versions that resolve this issue. Since this is a kernel-level vulnerability, applying the official kernel updates from the vendor or distribution is the recommended remediation.
Description
A memory corruption vulnerability in the Linux kernel's tracing subsystem related to the handling of the "STACKTRACE" histogram key has been resolved. The issue arises from improper handling of certain generic fields that leads to an unbounded memcpy operation, potentially causing a kernel panic due to a general protection fault. This affects specific Linux kernel versions used in the linux-hwe-edge product line.
