CVE-2022-1247: Fedoraproject Fedora

High severity, CVSS 7.0. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 36 only
• Linux Linux Kernel: affected versions not specified
• Red Hat Enterprise Linux: version 9.0 only
