Primary sources: NVD · CVE.org · FIRST EPSS

There is a denial of service vulnerability in some Huawei products. Due to improper memory management, memory leakage may occur in some special cases. Attackers can perform a series of operations to exploit this vulnerability. Successful exploit may cause a denial of service. Affected product versions include: CloudEngine 12800 versions V200R019C00SPC800; CloudEngine 5800 versions V200R019C00SPC800; CloudEngine 6800 versions V200R005C20SPC800, V200R019C00SPC800; CloudEngine 7800 versions V200R019C00SPC800; NE40E versions V800R011C00SPC200, V800R011C00SPC300, V800R011C10SPC100; NE40E-F versions V800R011C00SPC200, V800R011C10SPC100; NE40E-M versions V800R011C00SPC200, V800R011C10SPC100.

Remediation

Which version to upgrade to

Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.

No fix version is recorded for this entry. Check the references for vendor advisories.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
