Vulnerability from github – Published: 2024-02-15 06:31 – Updated: 2024-08-29 21:31

Details

The total size of the user-provided nmreq to nmreq_copyin() was first computed and then trusted during the copyin. This time-of-check to time-of-use bug could lead to kernel memory corruption.

On systems configured to include netmap in their devfs_ruleset, a privileged process running in a jail can affect the host environment.

Severity

7.8 (High)
