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