CVE-2024-50056
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().
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
