GHSA-7GR9-4F5W-GV8P

Vulnerability from github – Published: 2022-05-17 03:38 – Updated: 2022-05-17 03:38

Details

The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability.

Severity ?

7.8 (High)


                  
                    CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
