UBUNTU-CVE-2024-53111

Vulnérabilité dans linux-hwe-edge (UBUNTU-CVE-2024-53111)

Résumé

Vulnérabilité dans linux-hwe-edge (UBUNTU-CVE-2024-53111). Risque d'opérations non autorisées ou de divulgation. Exploitable via old_addr. Atténuation : mise à jour vers 6.8.0-1027.29~22.04.1 ou plus.

Description d'origine

La description telle que publiée par la source (souvent en anglais).

In the Linux kernel, the following vulnerability has been resolved: mm/mremap: fix address wraparound in move_page_tables() On 32-bit platforms, it is possible for the expression len + old_addr < old_end to be false-positive if len + old_addr wraps around. old_addr is the cursor in the old range up to which page table entries have been moved; so if the operation succeeded, old_addr is the end of the old region, and adding len to it can wrap. The overflow causes mremap() to mistakenly believe that PTEs have been copied; the consequence is that mremap() bails out, but doesn't move the PTEs back before the new VMA is unmapped, causing anonymous pages in the region to be lost. So basically if userspace tries to mremap() a private-anon region and hits this bug, mremap() will return an error and the private-anon region's contents appear to have been zeroed. The idea of this check is that old_end - len is the original start address, and writing the check that way also makes it easier to read; so fix the check by rearranging the comparison accordingly. (An alternate fix would be to refactor this function by introducing an "orig_old_start" variable or such.) Tested in a VM with a 32-bit X86 kernel; without the patch: ``` user@horn:~/big_mremap$ cat test.c #define _GNU_SOURCE #include #include #include #include #define ADDR1 ((void*)0x60000000) #define ADDR2 ((void*)0x10000000) #define SIZE 0x50000000uL int main(void) { unsigned char *p1 = mmap(ADDR1, SIZE…

Actions de réponse

Étapes concrètes et exemples de commandes que les équipes SOC/SRE doivent exécuter dans l'ordre

1
Identify exposure identify
```
grep -r 'linux-hwe-edge' . | 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 linux-hwe-edge 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 linux-hwe-edge to 6.8.0-1027.29~22.04.1
```
ステージング環境で 6.8.0-1027.29~22.04.1 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。
