CVE-2024-50215: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.6% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: assign dh_key to NULL after kfree_sensitive ctrl->dh_key might be used across multiple calls to nvmet_setup_dhgroup() for the same controller. So it's better to nullify it after release on error path in order to avoid double free later in nvmet_destroy_auth(). Found by Linux Verification Center (linuxtesting.org) with Svace.

Affected products

• Linux Linux Kernel: from 6.0, before 6.1.116 (fixed in 6.1.116); from 6.2, before 6.6.60 (fixed in 6.6.60); from 6.7, before 6.11.7 (fixed in 6.11.7); version 6.12 only
