{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: ccp - Fix a crash due to incorrect cleanup usage of kfree\n\nAnnotating a local pointer variable, which will be assigned with the\nkmalloc-family functions, with the `__cleanup(kfree)` attribute will\nmake the address of the local variable, rather than the address returned\nby kmalloc, passed to kfree directly and lead to a crash due to invalid\ndeallocation of stack address. According to other places in the repo,\nthe correct usage should be `__free(kfree)`. The code coincidentally\ncompiled because the parameter type `void *` of kfree is compatible with\nthe desired type `struct { ... } **`.",
