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
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 •

https://notcve.org/view.php?id=CVE-2020-24658
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 (after any vulnerable arrays). The reference value is written to the stack when the function runs out of registers to use for other temporary data. • 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 •
