Detailsinfo

A vulnerability was found in Linux Kernel up to 5.3.10 (Operating System) and classified as problematic. Affected by this issue is the function i2400m_op_rfkill_sw_toggle of the file drivers/net/wimax/i2400m/op-rfkill.c. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is availability. CVE summarizes:

A memory leak in the i2400m_op_rfkill_sw_toggle() function in drivers/net/wimax/i2400m/op-rfkill.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-6f3ef5c25cc7.

The weakness was presented 11/18/2019. This vulnerability is handled as CVE-2019-19051 since 11/18/2019. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1499.

Upgrading to version 5.3.11 eliminates this vulnerability.
