Vulnerability in Kernel (CVE-2022-50003)

Summary

Vulnerability in Kernel (CVE-2022-50003). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 5.10.140, 5.15.64, 5.19.6 or later.

Original description

The description as published by the source.

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

ice: xsk: prohibit usage of non-balanced queue id

Fix the following scenario:

ethtool -L $IFACE rx 8 tx 96
xdpsock -q 10 -t -z

Above refers to a case where user would like to attach XSK socket in
txonly mode at a queue id that does not have a corresponding Rx queue.
At this moment ice's XSK logic is tightly bound to act on a "queue pair",
e.g. both Tx and Rx queues at a given queue id are disabled/enabled and
both of them will get XSK pool assigned, which is broken for the presented
queue configuration. This results in the splat included at the bottom,
which is basically an OOB access to Rx ring array.

To fix this, allow using the ids only in scope of "combined" queues
reported by ethtool. However, logic should be rewritten to allow such
configurations later on, which would end up as a complete rewrite of the
control path, so let us go with this temporary fix.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

1
Identify exposure identify
```
grep -r 'Kernel' . | grep -v node_modules
```
リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で Kernel を grep し、稼働しているサービス・バージョンを把握する。
2
Apply patch patch
```
Upgrade Kernel to 5.10.140, 5.15.64, 5.19.6
```
ステージング環境で 5.10.140, 5.15.64, 5.19.6 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。
3
Post-deployment verification verify
```
Confirm patched version is live in production
```
パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
