Score 8.8 from GitHub Security Advisory (severity: HIGH) published 2026-08-06. a secondary CVSS source baseline 8.8; sources differ by 0.0.
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
In the Linux kernel, the following vulnerability has been resolved:
smb/client: Fix error code in smb2_aead_req_alloc()
The "*num_sgs" variable is a u32 so "ERR_PTR(*num_sgs)" doesn't work. We would have to do something similar to the previous line where it's cast to int and then long. However, it's simpler to store the return in an int ret variable.
This bug would eventually result in a crash when dereference the invalid error pointer.
EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).
