CVE-2022-23085

A user-provided integer option was passed to nmreqcopyin without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can affect the host...

CVE-2022-23084

The total size of the user-provided nmreq to nmreqcopyin 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 devfsruleset, a privileged process running in a jail can...

Design/Logic Flaw

A user-provided integer option was passed to nmreqcopyin without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can affect the host...

Memory corruption

The total size of the user-provided nmreq to nmreqcopyin 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 devfsruleset, a privileged process running in a jail can...

CVE-2022-23085 Potential jail escape vulnerabilities in netmap

A user-provided integer option was passed to nmreqcopyin without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can affect the host...

CVE-2022-23085

The FreeBSD Kernel is vulnerable to a privilege escalation flaw in the netmap component due to a numerical overflow in the nmreq_copyin() function. The issue arises from insufficient bounds checking of user-supplied integer options, which can lead to kernel memory corruption . An attacker who can...

CVE-2022-23084

CVE-2022-23084 concerns the FreeBSD netmap component. The vulnerability is a time-of-check to time-of-use bug in nmreq_copyin(): the total size of a user-provided nmreq is computed and then trusted during the copy, enabling kernel memory corruption. Impact requires netmap in devfs_ruleset; a priv...

CVE-2022-23084: Time-of-check Time-of-use (TOCTOU) Race Condition

The total size of the user-provided nmreq to nmreqcopyin 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 devfsruleset, a privileged process running in a jail can...

CVE-2022-23085: Out-of-bounds Write

A user-provided integer option was passed to nmreqcopyin without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can affect the host...
