Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: netconsole: fix wrong warning<br /> <br /> A warning is triggered when there is insufficient space in the buffer<br /> for userdata. However, this is not an issue since userdata will be sent<br /> in the next iteration.<br /> <br /> Current warning message:<br /> <br /> ------------[ cut here ]------------<br /> WARNING: CPU: 13 PID: 3013042 at drivers/net/netconsole.c:1122 write_ext_msg+0x3b6/0x3d0<br /> ? write_ext_msg+0x3b6/0x3d0<br /> console_flush_all+0x1e9/0x330<br /> <br /> The code incorrectly issues a warning when this_chunk is zero, which is<br /> a valid scenario. The warning should only be triggered when this_chunk<br /> is negative.
