CVE-2023-52677
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn the Linux kernel, the following vulnerability has been resolved: riscv: Check if the code to patch lies in the exit section Otherwise we fall through to vmalloc_to_page() which panics since the address does not lie in the vmalloc region.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

5.15.148, 6.1.75, 6.6.14, or 6.7.2 (or any later stable release)
- Identify the currently running Linux kernel version using 'uname -r'
- Determine which major kernel branch you're currently running (e.g., 5.15.x, 6.1.x, 6.2.x, 6.7.x)
- Upgrade to a kernel version that includes the fix: For 5.15.x branch, upgrade to >= 5.15.148; For 6.1.x branch, upgrade to >= 6.1.75; For 6.6.x branch, upgrade to >= 6.6.14; For 6.7.x branch, upgrade to >= 6.7.2
- Use your distribution's package manager to install the new kernel (e.g., 'apt update && apt upgrade' for Debian/Ubuntu, 'yum update' for RHEL/CentOS, or 'pacman -Syu' for Arch)
- Reboot the system to load the new kernel
- Verify the new kernel version is running with 'uname -r'
