RDMA\/mlx5: Fix stack out-of-bounds read in cc_params debugfs<\/p>\n
get_param() reads a congestion parameter as a u32 but formats it with the
\nsigned “%d” into an 11-byte stack buffer. A value with bit 31 set, such as
\n0x80000000, renders as “-2147483648n” whose full length is 12. snprintf()
\nstores only 11 bytes yet returns 12, so simple_read_from_buffer() treats 12
\nbytes as valid and reads one byte past lbuf[].<\/p>\n
Size the buffer for the widest unsigned decimal, format with “%u” to match
\nthe u32, and use scnprintf() so the length passed to
\nsimple_read_from_buffer() reflects the bytes actually stored.<\/p>\n","protected":false},"excerpt":{"rendered":"
