CVE-2024-50056 Details
Description
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: uvc: Fix ERR_PTR dereference in uvc_v4l2.c Fix potential dereferencing of ERR_PTR() in find_format_by_pix() and uvc_v4l2_enum_format(). Fix the following smatch errors: drivers/usb/gadget/function/uvc_v4l2.c:124 find_format_by_pix() error: 'fmtdesc' dereferencing possible ERR_PTR() drivers/usb/gadget/function/uvc_v4l2.c:392 uvc_v4l2_enum_format() error: 'fmtdesc' dereferencing possible ERR_PTR() Also, fix similar issue in uvc_v4l2_try_format() for potential dereferencing of ERR_PTR().
A vulnerability in the Linux kernel's USB gadget UVC (USB Video Class) functionality has been addressed. This issue involved the potential dereferencing of an error pointer (ERR_PTR) in several functions within the UVC V4L2 (Video for Linux 2) driver. The vulnerability could lead to incorrect handling of video formats, as the affected functions may have improperly processed format descriptions, potentially causing instability or unexpected behavior in applications that rely on UVC video streaming.
Users can upgrade to the patched version of the Linux kernel available in the Debian LTS repository. Instructions for applying this update can be found on the Debian LTS website.
