  "details": "In the Linux kernel, the following vulnerability has been resolved:  cachefiles: Fix potential UAF/KASAN warning  Currently, trace_cachefiles_coherency() is being passed a pointer to a __be64 lain over the coherency data in struct cachefiles_xattr so that it can display the first 8 bytes.  However, the data is of variable length and could even be 0 bytes.  This could lead to a UAF or KASAN warning.  Fix this by making sure the buffer has room for at least 8 bytes and that those 8 bytes are pre-cleared.  Further, those bytes are not 8-byte aligned, so fix the tracepoint to extract the data as four 2-byte words (they are 2-byte aligned) and reassemble the __be64.  The compiler will convert this into a single 8-byte load where the CPU supports it.",
