Details

In the Linux kernel, the following vulnerability has been resolved:

tipc: fix the msg->req tlv len check in tipcnlcompatnametabledumpheader

This is a follow-up for commit 974cb0e3e7c9 ("tipc: fix uninit-value in tipcnlcompatnametabledump") where it should have type casted sizeof(..) to int to work when TLVGETDATALEN() returns a negative value.

syzbot reported a call trace because of it:
