"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncachefiles: Fix potential UAF/KASAN warning\n\nCurrently, trace_cachefiles_coherency() is being passed a pointer to a\n__be64 lain over the coherency data in struct cachefiles_xattr so that it\ncan display the first 8 bytes. However, the data is of variable length and\ncould even be 0 bytes. This could lead to a UAF or KASAN warning.\n\nFix this by making sure the buffer has room for at least 8 bytes and that\nthose 8 bytes are pre-cleared.\n\nFurther, those bytes are not 8-byte aligned, so fix the tracepoint to\nextract the data as four 2-byte words (they are 2-byte aligned) and\nreassemble the __be64. The compiler will convert this into a single 8-byte\nload where the CPU supports it."
