    Miscompilation in cortex-m-rt 0.7.1 and 0.7.2

    GHSA-xw5j-gv2g-mjm2

    Affected
    • crates.io cortex-m-rt >= 0.7.0, < 0.7.3
    Fixed in
    0.7.3· Vendor fix available
    Issue
    Version 0.7.1 of the cortex-m-rt crate introduced a regression causing the stack to NOT be eight-byte aligned prior to calling main (or any other specified entrypoint), violating the [stack ABI of AAPCS32], the default ABI used by all Cortex-M targets. This regression is also present in version 0.7.2 of the cortex-m-rt crate. This regression can cause certain compiler optimizations (which assume the eight-byte alignment) to produce incorrect behavior at runtime. This incorrect behavior has been [observed in real-world applications]. It is advised that ALL users of v0.7.1 and v0.7.2 of the cortex-m-rt crate update to the latest version (v0.7.3), AS SOON AS POSSIBLE. Users of v0.7.0 and prior versions of cortex-m-rt are not affected by this regression. It will be necessary to rebuild all affected firmware binaries, and flash or deploy the new firmware binaries to affected devices. [stack ABI of AAPCS32]:…

    Recommended action: Upgrade to 0.7.3 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
