This causes smb_block_write() to read 32 bytes from the\nadvanced data buffer pointer, reading past the end of the input buffer.\n\nFix this by calculating block_len using cur_len and advancing the buffer\nand address pointers by block_len.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
