Created: May 30, 2024 Updated: Jun 8, 2026

Resolved Date: Jun 8, 2026

Found In Version: 10.21.20.1

Fix Version: 10.21.20.27

Severity: Standard

Applicable for: Wind River Linux LTS 21

Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:

ipv6: Fix potential uninit-value access in __ip6_make_skb()

As it was done in commit fc1092f51567 ("ipv4: Fix uninit-value access in
__ip_make_skb()") for IPv4, check FLOWI_FLAG_KNOWN_NH on fl6->flowi6_flags
instead of testing HDRINCL on the socket to avoid a race condition which
causes uninit-value access.
