CVE-2024-42069: net: mana: Fix possible double free in error handling path

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: 0.23% (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 1864b8224195d0e43ddb92a8151f54f6562090cc, 3243e64eb4d897c3eeb48b2a7221ab5a95e1282a, ed45c0a0b662079d4c0e518014cc148c753979b4; azl3 kernel 6.6.35.1-5 on Azure Linux 3.0 6.6.43.1-7; azl3 kernel 6.6.43.1-7 on Azure Linux 3.0 6.6.43.1-7.
  • Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 5.5.

Low priority for now. Upgrade to Linux Linux 1864b8224195d0e43ddb92a8151f54f6562090cc, 3243e64eb4d897c3eeb48b2a7221ab5a95e1282a, ed45c0a0b662079d4c0e518014cc148c753979b4; azl3 kernel 6.6.35.1-5 on Azure Linux 3.0 6.6.43.1-7; azl3 kernel 6.6.43.1-7 on Azure Linux 3.0 6.6.43.1-7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix possible double free in error handling path When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), callback function adev_release calls kfree(madev). We shouldn't call kfree(madev) again in the error handling path. Set 'madev' to NULL.
