CVE-2024-53104

CVE-2024-53104 is an out-of-bounds write (CWE-787) in the Linux kernel's uvcvideo (USB Video Class) driver: uvc_parse_format does not skip frames of type UVC_VS_UNDEFINED, but those frame types were not accounted for when sizing the frames buffer in uvc_parse_streaming. The flaw is triggered when the kernel parses format/frame descriptors from a USB camera device, so a crafted or nonconforming USB video descriptor can corrupt adjacent kernel memory. An attacker with local, low-privileged access (CVSS 3.1: AV:L/AC:L/PR:L, 7.8 High) can gain kernel memory corruption with high impact to confidentiality, integrity and availability, typically yielding local privilege escalation. Any Linux system or Android device running a kernel that ships the UVC driver is in scope, including Debian and other distributions built from affected kernel sources. Exploitation is confirmed in the wild: the vulnerability was added to CISA's KEV on 2025-02-05, Google fixed it as an actively exploited flaw in the March 2025 Android Security Update, and EPSS currently estimates a 3.4% (88th percentile) probability of exploitation over the next 30 days.

What to do: Upgrade to a Linux kernel version that contains the uvcvideo fix (apply updated kernel packages from your distribution, e.g. Debian), and for Android devices install the March 2025 Android Security Bulletin patches or later. Follow the CISA KEV required action by applying vendor mitigations or discontinuing use if patches are unavailable. To gauge exposure on unpatched hosts, check whether the UVC driver is loaded (e.g. 'lsmod | grep uvcvideo') and restrict untrusted USB video devices until patched.
