Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 5.3.7 (Operating System). Affected by this issue is the function ca8210_probe of the file drivers/net/ieee802154/ca8210.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 ca8210_probe() function in drivers/net/ieee802154/ca8210.c in the Linux kernel before 5.3.8 allows attackers to cause a denial of service (memory consumption) by triggering ca8210_get_platform_data() failures, aka CID-6402939ec86e.

The weakness was disclosed 11/18/2019. This vulnerability is handled as CVE-2019-19075 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 5.3.8 eliminates this vulnerability.

The entries VDB-145896, VDB-145895, VDB-145894 and VDB-145893 are pretty similar. Once again VulDB remains the best source for vulnerability data.
