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 { ... } **`.
