CVE-2024-45555
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMemory corruption can occur if an already verified IFS2 image is overwritten, bypassing boot verification. This allows unauthorized programs to be injected into security-sensitive images, enabling the booting of a tampered IFS2 system image.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMemory corruption occurs when an already verified IFS2 (IBM system image) is overwritten, bypassing boot verification checks. This allows attackers to inject unauthorized code into security-sensitive system images and boot tampered IFS2 images, achieving code execution at the firmware/boot level.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify firmware model and versionRetrieve the system firmware information from the device or system documentation. Look for the chipset or firmware identifier (e.g., Msm8996au, Qam8255p, Qam8295p, Qam8620p, Qam8650p, Qam8775p, Qamsrv1h, Qamsrv1m) and its version number.Affected if The firmware model matches any of the affected Qualcomm variants listed in the CVE and is running any version.
-
Determine if IFS2 image verification is in useCheck system boot configuration or firmware settings to see if IFS2 (IBM system image) verification is enabled. This may be visible in boot logs, secure boot configuration, or firmware management interfaces.Affected if IFS2 image verification is configured and the system relies on the boot verification mechanism described in the CVE.
-
Inspect boot logs for verification bypass indicatorsExamine boot logs, secure boot audit logs, or firmware integrity logs for any warnings or failures related to IFS2 image verification, memory integrity checks, or image authentication. Look for unexpected modifications or verification failures.Affected if Boot logs show signs of IFS2 verification bypass, unexpected image modifications, or memory corruption events affecting system images.
-
Check for unauthorized code injection in system imagesCompare the current IFS2 system images against known-good or reference images if available. Look for unexpected changes, additional code sections, or modifications to verified boot images.Affected if IFS2 images contain unexpected code, have been modified after verification, or differ from expected baseline configurations.
A system is affected if it runs any of the listed Qualcomm firmware variants with IFS2 image verification enabled, and evidence shows the boot verification can be bypassed or verified images can be overwritten in memory.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement integrity protection for verified IFS2 images in memory and enforce re-verification before boot. Patch the memory corruption vulnerability to prevent modification of already-verified boot images.
