CVE-2024-57925: ksmbd: fix a missing return value check bug

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.20% (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 271ae0edbfc942795c162e6cf20d2bc02bd7fde4, 2976e91a3e569cf2c92c9f71512c0ab1312fe965, 4c16e1cadcbcaf3c82d5fc310fbd34d0f5d0db7c; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.78.1-3.

Low priority for now. Upgrade to Linux Linux 271ae0edbfc942795c162e6cf20d2bc02bd7fde4, 2976e91a3e569cf2c92c9f71512c0ab1312fe965, 4c16e1cadcbcaf3c82d5fc310fbd34d0f5d0db7c; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.78.1-3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix a missing return value check bug In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct() fails to allocate a node, it returns a NULL pointer to the in_work pointer. This can lead to an illegal memory write of in_work->response_buf when allocate_interim_rsp_buf() attempts to perform a kzalloc() on it. To address this issue, incorporating a check for the return value of ksmbd_alloc_work_struct() ensures that the function returns immediately upon allocation failure, thereby preventing the aforementioned illegal memory access.
