CVE-2022-50101 (GCVE-0-2022-50101)

Vulnerability from cvelistv5 – Published: 2025-06-18 11:02 – Updated: 2026-08-05 08:57

Title

video: fbdev: vt8623fb: Check the size of screen before memset_io()

Summary

In the Linux kernel, the following vulnerability has been resolved: video: fbdev: vt8623fb: Check the size of screen before memset_io() In the function vt8623fb_set_par(), the value of 'screen_size' is calculated by the user input. If the user provides the improper value, the value of 'screen_size' may larger than 'info->screen_size', which may cause the following bug: [ 583.339036] BUG: unable to handle page fault for address: ffffc90005000000 [ 583.339049] #PF: supervisor write access in kernel mode [ 583.339052] #PF: error_code(0x0002) - not-present page [ 583.339074] RIP: 0010:memset_orig+0x33/0xb0 [ 583.339110] Call Trace: [ 583.339118] vt8623fb_set_par+0x11cd/0x21e0 [ 583.339146] fb_set_var+0x604/0xeb0 [ 583.339181] do_fb_ioctl+0x234/0x670 [ 583.339209] fb_ioctl+0xdd/0x130 Fix the this by checking the value of 'screen_size' before memset_io().

An unprivileged local user in the video group or with seat/uaccess rights can open the device and invoke the ioctl.\nUI:N - Exploitation requires only issuing the ioctl from the attacker\u0027s own process; no victim action such as mounting a filesystem or opening a crafted file is needed.\nS:U - This is a standard in-kernel framebuffer driver bug that affects the host kernel authority only; it does not cross a VM, IOMMU, or other security boundary.\nC:H - The bug is a user-controlled out-of-bounds write via memset_io() past the mapped framebuffer. Per scoring guidance, memory-corruption primitives of this class are treated as enabling high confidentiality impact when exploitation is considered.\nI:H - memset_io() writes past info-\u003escreen_size into ioremapped framebuffer memory with an attacker-controlled length, which is an out-of-bounds write and is scored as high integrity impact.\nA:H - The demonstrated impact is a kernel page fault/oops in memset_io() when the write walks off the mapped region, which is a full availability compromise of the kernel."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
