Linux Kernel UVC Video Format Parsing Out-of-Bounds Write Vulnerability
CVE-2024-53104 Published on December 2, 2024
media: uvcvideo: Skip parsing frames of type UVC_VS_UNDEFINED in uvc_parse_format
In the Linux kernel, the following vulnerability has been resolved:
media: uvcvideo: Skip parsing frames of type UVC_VS_UNDEFINED in uvc_parse_format
This can lead to out of bounds writes since frames of this type were not
taken into account when calculating the size of the frames buffer in
uvc_parse_streaming.
Known Exploited Vulnerability
This Linux Kernel Out-of-Bounds Write Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. Linux kernel contains an out-of-bounds write vulnerability in the uvc_parse_streaming component of the USB Video Class (UVC) driver that could allow for physical escalation of privilege.
The following remediation steps are recommended / required by February 26, 2025: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Vulnerability Analysis
CVE-2024-53104 is exploitable with local system access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. This vulnerability is known to be actively exploited by threat actors. The potential impact of an exploit of this vulnerability is considered to be very high.
Weakness Type
What is a Memory Corruption Vulnerability?
The software writes data past the end, or before the beginning, of the intended buffer. Typically, this can result in corruption of data, a crash, or code execution. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent write operation then produces undefined or unexpected results.
CVE-2024-53104 has been classified to as a Memory Corruption vulnerability or weakness.
