      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nevm: terminate and bound the evm_xattrs read buffer\n\nevm_read_xattrs() allocates size + 1 bytes, fills them from the list of\nenabled xattrs, and then passes strlen(temp) to\nsimple_read_from_buffer(). When no configured xattrs are enabled, the\nfill loop stores nothing and temp[0] remains uninitialized, so strlen()\nreads beyond initialized memory.\n\nExplicitly terminate the buffer after allocation, use snprintf() for\neach formatted line, and pass the accumulated length, without risk of\ntruncation, to simple_read_from_buffer().",
