CVSS: 3.7EPSS: 0%CPEs: 5EXPL: 0CVE-2024-7883 – CMSE secure state may leak from stack to floating-point registers
https://notcve.org/view.php?id=CVE-2024-7883
31 Oct 2024 — When using Arm Cortex-M Security Extensions (CMSE), Secure stack contents can be leaked to Non-secure state via floating-point registers when a Secure to Non-secure function call is made that returns a floating-point value and when this is the first use of floating-point since entering Secure state. This allows an attacker to read a limited quantity of Secure stack contents with an impact on confidentiality. This issue is specific to code generated using LLVM-based compilers. • https://developer.arm.com/Arm%20Security%20Center/Cortex-M%20Security%20Extensions%20Vulnerability • CWE-226: Sensitive Information in Resource Not Removed Before Reuse •

24 Dec 2020 — Arm Compiler 5 through 5.06u6 has an error in a stack protection feature designed to help spot stack-based buffer overflows in local arrays. When this feature is enabled, a protected function writes a guard value to the stack prior to (above) any vulnerable arrays in the stack. The guard value is checked for corruption on function return; corruption leads to an error-handler call. In certain circumstances, the reference value that is compared against the guard value is itself also written to the stack (afte... • https://developer.arm.com/support/arm-security-updates/arm-compiler-5-stack-protection • CWE-770: Allocation of Resources Without Limits or Throttling CWE-787: Out-of-bounds Write •
