  "summary": "media: cedrus: fix memory leak in cedrus_init_ctrls()",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: cedrus: fix memory leak in cedrus_init_ctrls()\n\nIn cedrus_init_ctrls(), the V4L2 control handler is initialized before\nallocating memory for ctx->ctrls. 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->ctrls 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.",
