Description
In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Fix a crash due to incorrect cleanup usage of kfree Annotating a local pointer variable, which will be assigned with the kmalloc-family functions, with the `__cleanup(kfree)` attribute will make the address of the local variable, rather than the address returned by kmalloc, passed to kfree directly and lead to a crash due to invalid deallocation of stack address. According to other places in the repo, the correct usage should be `__free(kfree)`. The code coincidentally compiled because the parameter type `void *` of kfree is compatible with the desired type `struct { ... } **`.
