CVE-2021-3483

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.12-rc6

Description A flaw was found in the Nosy driver in the Linux kernel, allowing a device to be inserted twice into a doubly-linked list. This leads to a use-after-free when one of these devices is removed, posing a threat to confidentiality, integrity, and system availability.

Recommendations For versions prior to 5.12-rc6, update to kernel version 5.12-rc6 or later to resolve the issue. As a temporary workaround, consider restricting access to the Nosy driver to minimize the risk of exploitation.
