CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HIn the Linux kernel, the following vulnerability has been resolved: ipv6: add NULL checks for idev in SRv6 paths __in6_dev_get() can return NULL when the device has no IPv6 configuration (e.g. MTU < IPV6_MIN_MTU or after NETDEV_UNREGISTER). Add NULL checks for idev returned by __in6_dev_get() in both seg6_hmac_validate_skb() and ipv6_srh_rcv() to prevent potential NULL pointer dereferences. A flaw was found in the Linux kernel. Missing null pointer checks in the IPv6 Segment Routing (SRv6) implementation, specifically within the `seg6_hmac_validate_skb()` and `ipv6_srh_rcv()` functions, can occur when an IPv6 device lacks proper configuration. This oversight may allow an attacker to trigger a null pointer dereference, potentially leading to a system crash and a Denial of Service (DoS).
