According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : xfrm: esp: avoid in-place decrypt on shared skb fragsCVE-2026-43284 crypto: algifaead - Revert to operating...

kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...

CVE-2026-46300

CVE-2026-46300 ("Fragnesia") is a local privilege escalation in the Linux kernel's ESP/XFRM (IPsec ESP-in-TCP) subsystem. The root cause is that skb_try_coalesce() fails to propagate the SKBFL_SHARED_FRAG marker when transferring paged fragments, causing ESP to skip skb_cow_data() and decrypt in ...
