Linux kernel 安全漏洞

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 the use of socket-level IV buffers in asynchronous AEAD requests within algifaead. This can lead ...

PT-2026-43895

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the algif aead component where AF ALG AEAD AIO requests utilize a socket-wide IV Initialization Vector buffer during processing. For asynchronous requests, subsequent...

UBUNTU-CVE-2026-46028

In the Linux kernel, the following vulnerability has been resolved: crypto: algifaead - snapshot IV for async AEAD requests AFALG AEAD AIO requests currently use the socket-wide IV buffer during request processing. For async requests, later socket activity can update that shared state before the...

Insecure Randomness

Overview Affected versions of this package are vulnerable to Insecure Randomness due to the HKDFexpand and EVPHPKECTXexport functions returning a zero-filled byte array on failure, which is then used as key material for AEAD encryption. An attacker can predict and exploit the deterministic,...
