CVE-2024-46792 Details
Description
In the Linux kernel, the following vulnerability has been resolved: riscv: misaligned: Restrict user access to kernel memory raw_copy_{to,from}_user() do not call access_ok(), so this code allowed userspace to access any virtual memory address.
A vulnerability in the Linux kernel's handling of misaligned memory access on RISC-V architectures allowed userspace to access arbitrary kernel memory addresses. This issue arose because the functions raw_copy_to_user and raw_copy_from_user did not properly check memory access permissions, enabling unauthorized access to virtual memory. The vulnerability has been addressed by modifying these functions to include the necessary access checks.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel official website.
