      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nKEYS: encrypted: fix integer overflow of datablob_len\n\nencrypted_key_alloc() stores datablob_len in a u16. It is computed from\nmultiple string and payload lengths. If the result exceeds U16_MAX, the\nassignment truncates the allocation size. KASAN reports a 32760-byte\nslab-out-of-bounds write when __ekey_init() copies the master key\ndescription into the undersized buffer.\n\nThe total payload length stored in key->datalen is also a u16. Use\ncheck_add_overflow() to reject values that do not fit either destination,\nand use kzalloc_flex() for the flexible-array allocation.",
