In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
Input: rmi_smbus – fix out-of-bounds read in rmi_smb_write_block()<\/p>\n
When chunking writes into SMBus blocks in rmi_smb_write_block(), the
\nloop calculates block_len using the original total length (len) instead
\nof the remaining length (cur_len).<\/p>\n
If len is greater than 32 bytes (SMB_MAX_COUNT), block_len remains 32
\nfor every iteration, even on the final partial chunk where fewer than 32
\nbytes remain. This causes smb_block_write() to read 32 bytes from the
\nadvanced data buffer pointer, reading past the end of the input buffer.<\/p>\n
Fix this by calculating block_len using cur_len and advancing the buffer
\nand address pointers by block_len.<\/p>\n","protected":false},"excerpt":{"rendered":"
