Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A vulnerability in the Linux kernel has been resolved. The issue occurs when the dsa tree setup() function fails after successfully probing the last switch in the tree, resulting in a use-after-free error. This happens because the routing table elements pointing to the ports of the failed switch are not properly removed. The vulnerability can lead to a slab-use-after-free bug, as reported by the KASAN (Kernel Address Sanitizer). The estimated number of potentially affected devices is not provided, and there is no information about real-world incidents where this issue was exploited.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
