VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.50
Description The issue is related to a use after free vulnerability in the dequeue rx() function of the Linux kernel. This vulnerability can be exploited to cause a denial of service. The problem occurs because the skb cannot be dereferenced after calling vcc->push() due to the skb being released.
Recommendations To resolve the issue, update to Linux kernel version 6.6.50 or later. As a temporary workaround, consider restricting access to the vulnerable dequeue rx() function until a patch is available.
