Description
Description
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.
