CVE-2026-45958 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/exynos: vidi: fix to avoid directly dereferencing user pointer In vidi_connection_ioctl(), vidi->edid(user pointer) is directly dereferenced in the kernel. This allows arbitrary kernel memory access from the user space, so instead of directly accessing the user pointer in the kernel, we should modify it to copy edid to kernel memory using copy_from_user() and use it.
A vulnerability exists in the Linux kernel's Exynos video driver, specifically within the 'vidi_connection_ioctl' function. The issue arises because the 'edid' user pointer is directly dereferenced in the kernel, leading to arbitrary access of kernel memory from user space. This vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed by modifying the driver to use 'copy_from_user()' to safely transfer 'edid' data from user space to a kernel buffer, preventing direct dereferencing of user pointers.
