Memory Copy Vulnerability in Linux Kernel Affecting i.MX DSP Cores

CVE-2023-53434

What is CVE-2023-53434?

A flaw in the Linux Kernel concerning the remoteproc management of the i.MX DSP Cores has been identified. This vulnerability arises from the inability to perform memory operations correctly due to strict hardware specifications that only allow 32-bit writes. Violating this rule can lead to a Kernel panic. To mitigate the risk, a custom memory copy implementation and memset functions have been added specifically for handling this limitation, ensuring better memory management and stability when interfacing with the affected DSP cores.
