CVE-2024-53151 high CVSS 7.5

Vulnerability in Linux kernel (CVE-2024-53151)

Summary

Vulnerability in Linux kernel (CVE-2024-53151). Risk of unauthorized operations or information disclosure.

Original description

The description as published by the source.

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

svcrdma: Address an integer overflow

Dan Carpenter reports:

Commit 78147ca8b4a9 ("svcrdma: Add a "parsed chunk list" data
structure") from Jun 22, 2020 (linux-next), leads to the following
Smatch static checker warning:

net/sunrpc/xprtrdma/svc_rdma_recvfrom.c:498 xdr_check_write_chunk()
warn: potential user controlled sizeof overflow 'segcount * 4 * 4'

net/sunrpc/xprtrdma/svc_rdma_recvfrom.c
488 static bool xdr_check_write_chunk(struct svc_rdma_recv_ctxt *rctxt)
489 {
490 u32 segcount;
491 __be32 *p;
492
493 if (xdr_stream_decode_u32(&rctxt->rc_stream, &segcount))
^^^^^^^^

494                 return false;
495
496         /* A bogus segcount causes this buffer overflow check to fail. */
497         p = xdr_inline_decode(&rctxt->rc_stream,

--> 498 segcount * rpcrdma_segment_maxsz * sizeof(*p));

segcount is an untrusted u32. On 32bit systems anything >= SIZE_MAX / 16 will
have an integer overflow and some those values will be accepted by
xdr_inline_decode().

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Audit SBOM/dependencies to find affected services.

Response actions

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

  1. 1
    Identify exposure identify 
    Audit SBOM/dependencies for affected components.

    資産台帳・SBOM・依存マニフェストで Linux kernel を使っているサービスとバージョンを洗い出す。

  2. 2
    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。
