CVE-2022-49780: scsi: target: tcm_loop: Fix possible name leak in tcm_loop_setup_hba_bus()

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: 0.21% (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 28f7ff5e7559d226e63c7c5de74eb075a83d8c53, 41a6b8b527a5957fab41c3c05e25ad125268e2e9, 75205f1b47a88c3fac4f30bd7567e89b2887c7fd.

Low priority for now. Upgrade to Linux Linux 28f7ff5e7559d226e63c7c5de74eb075a83d8c53, 41a6b8b527a5957fab41c3c05e25ad125268e2e9, 75205f1b47a88c3fac4f30bd7567e89b2887c7fd or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: scsi: target: tcm_loop: Fix possible name leak in tcm_loop_setup_hba_bus() If device_register() fails in tcm_loop_setup_hba_bus(), the name allocated by dev_set_name() need be freed. As comment of device_register() says, it should use put_device() to give up the reference in the error path. So fix this by calling put_device(), then the name can be freed in kobject_cleanup(). The 'tl_hba' will be freed in tcm_loop_release_adapter(), so it don't need goto error label in this case.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
