CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's greybus audio subsystem, where insufficient validation of topology section sizes can lead to out-of-bounds reads during data parsing. This flaw may allow an attacker to exploit the system by providing a module with manipulated size parameters, potentially leading to memory corruption or arbitrary code execution. Linux system administrators and developers utilizing the greybus audio framework should prioritize applying the patch to mitigate this risk.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: greybus: audio: bound the topology section sizes against the fetched size gb_audio_gb_get_topology() fetches a topology blob of a module-supplied size, and gbaudio_tplg_parse_data() then walks it by adding the module-supplied size_dais, size_controls and size_widgets fields to form the control, widget and route section offsets. Those le32 sizes are never checked against the fetched blob, so a module reporting a small topology size but large section sizes makes the offsets point past the allocation, and parsing reads out of bounds. Reject a topology whose section sizes do not fit within the fetched size before it is parsed.
