CVE-2024-36901

CVSS v2.0

6.8

Medium

VectorAV:N/AC:L/Au:S/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.37
Description A vulnerability in the Linux kernel's IPv6 implementation allows for a NULL pointer dereference in the ip6 output() function. This can cause a general protection fault and potentially lead to a denial-of-service. The issue is related to the ip6 dst idev() function returning NULL in certain cases. Most places in the IPv6 stack handle a NULL idev fine, but not in this specific case.
Recommendations To resolve this issue, update the Linux kernel to version 6.6.37 or later. This update includes the fix for the NULL pointer dereference in ip6 output(). If updating is not possible, consider disabling the ip6 output() function or restricting its use as a temporary workaround until a patch can be applied.
