Detailsinfo

A vulnerability has been found in Linux Kernel (Operating System) (unknown version) and classified as problematic. Affected by this vulnerability is the function rose_connect of the component Rose Driver. The manipulation with an unknown input leads to a race condition vulnerability. The CWE definition for the vulnerability is CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. The impact remains unknown. The summary by CVE is:

An issue found in linux-kernel that leads to a race condition in rose_connect(). The rose driver uses rose_neigh->use to represent how many objects are using the rose_neigh. When a user wants to delete a rose_route via rose_ioctl(), the rose driver calls rose_del_node() and removes neighbours only if their “count” and “use” are zero.

The weakness was published 08/31/2022. The advisory is shared at access.redhat.com. This vulnerability is known as CVE-2022-1247 since 04/05/2022. Technical details and also a exploit are known. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 10/10/2022).

It is declared as proof-of-concept.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
