CVE-2025-68782: scsi: target: Reset t_task_cdb pointer in error case

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.69% (FIRST EPSS); higher than 53.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0260ad551b0815eb788d47f32899fbcd65d6f128, 0d36db68fdb8a3325386fd9523b67735f944e1f3, 45fd86b444105c8bd07a763f58635c87e5dc7aea; azl3 kernel 6.6.119.3-3 on Azure Linux 3.0 6.6.121.1-1.

Low priority for now. Upgrade to Linux Linux 0260ad551b0815eb788d47f32899fbcd65d6f128, 0d36db68fdb8a3325386fd9523b67735f944e1f3, 45fd86b444105c8bd07a763f58635c87e5dc7aea; azl3 kernel 6.6.119.3-3 on Azure Linux 3.0 6.6.121.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: scsi: target: Reset t_task_cdb pointer in error case If allocation of cmd->t_task_cdb fails, it remains NULL but is later dereferenced in the 'err' path. In case of error, reset NULL t_task_cdb value to point at the default fixed-size buffer. Found by Linux Verification Center (linuxtesting.org) with SVACE.
