In the Linux kernel, the following vulnerability has been resolved:
block/rnbd-srv: Check for unlikely string overflow
Since "dev_search_path" can technically be as large as PATH_MAX,
there was a risk of truncation when copying it and a second string
into "full_path" since it was also PATH_MAX sized. The W=1 builds were
reporting this warning:
drivers/block/rnbd/rnbd-srv.c: In function 'process_msg_open.isra':
drivers/block/rnbd/rnbd-srv.c:616:51: warning: '%s' directive output may be truncated writing up to 254 bytes into a region of size between 0 and 4095 [-Wformat-truncation=]
616 | snprintf(full_path, PATH_MAX, "%s/%s",
| ^~
In function 'rnbd_srv_get_full_path',
inlined from 'process_msg_open.isra' at drivers/block/rnbd/rnbd-srv.c:721:14: drivers/block/rnbd/rnbd-srv.c:616:17: note: 'snprintf' output between 2 and 4351 bytes into a destination of size 4096
616 | snprintf(full_path, PATH_MAX, "%s/%s",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
617 | dev_search_path, dev_name);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~
To fix this, unconditionally check for truncation (as was already done
for the case where "%SESSNAME%" was present).
