Summary

In the Linux kernel, the following vulnerability has been resolved: media: cedrus: fix memory leak in cedrus_init_ctrls() In cedrus_init_ctrls(), the V4L2 control handler is initialized before allocating memory for ctx->ctrls. If this allocation fails, the function returns -ENOMEM without freeing the previously allocated handler resources, leading to a memory leak. Fix this by calling v4l2_ctrl_handler_free() on the ctx->ctrls allocation failure path. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1.1. An x86_64 allyesconfig build showed no new warnings. As we do not have an Allwinner SoC or board with a Cedrus VPU available to test with, no runtime testing was able to be performed.

If this allocation fails, the function\nreturns -ENOMEM without freeing the previously allocated handler\nresources, leading to a memory leak.\n\nFix this by calling v4l2_ctrl_handler_free() on the ctx-\u003ectrls allocation\nfailure path.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still\npresent in v7.1.1.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have an\nAllwinner SoC or board with a Cedrus VPU available to test with, no\nruntime testing was able to be performed."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
