CVE-2024-38608: net/mlx5e: Fix netif state handling

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.26% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 3d5918477f94e4c2f064567875c475468e264644, 70eca80d98a44f47cd1633d0c20bda8ae546b4d1, 96e3eeccea9b55ca9c6a18a5a59ee3d6f12e0fb3.

Low priority for now. Upgrade to Linux Linux 3d5918477f94e4c2f064567875c475468e264644, 70eca80d98a44f47cd1633d0c20bda8ae546b4d1, 96e3eeccea9b55ca9c6a18a5a59ee3d6f12e0fb3 or later.

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix netif state handling mlx5e_suspend cleans resources only if netif_device_present() returns true. However, mlx5e_resume changes the state of netif, via mlx5e_nic_enable, only if reg_state == NETREG_REGISTERED. In the below case, the above leads to NULL-ptr Oops[1] and memory leaks: mlx5e_probe _mlx5e_resume mlx5e_attach_netdev mlx5e_nic_enable <-- netdev not reg, not calling netif_device_attach() register_netdev <-- failed for some reason. ERROR_FLOW: _mlx5e_suspend <-- netif_device_present return false, resources aren't freed :( Hence, clean resources in this case as well.
