CVE-2026-23475

A flaw was found in the Linux kernel's Serial Peripheral Interface SPI component. The system's per-CPU statistics for the SPI controller were not allocated until after the controller was registered. This created a window where a local user or process could access system files sysfs attributes...

Linux Kernel Security Vulnerabilities

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from improper timing of the hierarchical structure creation process. This vulnerability may lead to...

Linux Kernel Security Vulnerabilities

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the improper timing of the SPI controller’s statistics allocation. This vulnerability may lead to null...

CVE-2025-66442

A flaw was found in Mbed TLS and TF-PSA-Crypto. This vulnerability is a compiler-induced timing side channel that occurs when the LLVM compiler's select-optimize feature is enabled. A remote attacker could potentially exploit this timing difference during RSA and CBC/ECB decryption operations to...

CVE-2025-66442: Covert Timing Channel

In Mbed TLS through 4.0.0, there is a compiler-induced timing side channel in RSA and CBC/ECB decryption that only occurs with LLVM's select-optimize feature. TF-PSA-Crypto through 1.0.0 is also affected...

Covert Timing Channel

Overview Affected versions of this package are vulnerable to Covert Timing Channel via timing differences in RSA and CBC/ECB decryption operations when the LLVM compiler's select-optimize feature is enabled. An attacker can infer sensitive information, such as cryptographic keys, by analyzing the...

CVE-2025-66442

The Mbed TLS library through version 4.0.0 and TF-PSA-Crypto through version 1.0.0 are vulnerable to a compiler-induced timing side channel . This issue specifically affects RSA and CBC/ECB decryption operations and only occurs when using the LLVM select-optimize feature. No specific exploit deta...

MBed TLS security vulnerabilities

Mbed TLS is an open-source, portable, easy-to-use, readable, and flexible SSL library developed by Mbed TLS. Mbed TLS versions 4.0.0 and earlier, as well as TF-PSA-Crypto versions 1.0.0 and earlier, have security vulnerabilities. These vulnerabilities stem from compiler-induced timing side...
