  "details": "In the Linux kernel, the following vulnerability has been resolved:  platform/x86: hp-bioscfg: fix off-by-one write in hp_get_string_from_buffer()  hp_get_string_from_buffer() clamps the converted string length against the destination buffer size with \"size \u003e dst_size\", so when the converted length is exactly equal to dst_size, conv_dst_size is left at dst_size and the unconditional NUL terminator write  \tdst[conv_dst_size] = 0;  lands one byte past the destination buffer. This is the same shape of bug as the previously fixed off-by-one in hp_convert_hexstr_to_str(): the buffer is sized correctly for the content, but the terminator write is never checked against that size.  Fix by changing the comparison to \"\u003e=\" so conv_dst_size is always left with room for the terminator.  All fixed-size destinations that reach this function (path[512], current_value[512], current_password/current_value[64], and the per-entry buffers in encodings[][512] and prerequisites[][512]) are affected.",
