  "details": "In the Linux kernel, the following vulnerability has been resolved:  KEYS: encrypted: fix integer overflow of datablob_len  encrypted_key_alloc() stores datablob_len in a u16. It is computed from multiple string and payload lengths. If the result exceeds U16_MAX, the assignment truncates the allocation size. KASAN reports a 32760-byte slab-out-of-bounds write when __ekey_init() copies the master key description into the undersized buffer.  The total payload length stored in key-\u003edatalen is also a u16. Use check_add_overflow() to reject values that do not fit either destination, and use kzalloc_flex() for the flexible-array allocation.",
