  "details": "In the Linux kernel, the following vulnerability has been resolved:  cachefiles: Fix error return when vfs_mkdir() fails  When vfs_mkdir() fails, the error code is not extracted from the returned error pointer. This causes mkdir_error to be reached with ret=0, which leads to returning ERR_PTR(0) (NULL) instead of a proper error pointer.  Fix this by extracting the error code from the error pointer when vfs_mkdir() fails.",
