Astra Linux – Vulnerability in Linux

In kernel/bpf/verifier.c in the Linux kernel before version 5.12.13, a branch prediction can be mispredicted e.g., due to type confusion, allowing a non-privileged BPF program to access arbitrary memory locations through a side-channel attack, known as CID-9183671af6db...

CVE-2024-42265

CVE-2024-42265 pertains to the Linux kernel and was resolved by protecting the fetch of ->fd[fd] in do_dup2() from mispredictions. The issue arose when a mispredicted path could cause tofree = fdt->fd[fd] to be speculatively executed, which is incorrect for bounds reasons. The documented fi...

Vulnerability of microprogramming software for Intel, AMD, ARM, and IBM processors: This vulnerability arises due to the creation of racing states in a speculative mode, which can lead to access to already freed memory areas. If the processor mispredicts the branching in the code, it allows a hacker to gain access to protected memory.

The vulnerability of microprogramming software for processors from Intel, AMD, ARM, and IBM arises from the existence of speculative execution states that can lead to access to already freed memory areas, if the processor mispredicts branch instructions in the code. Exploiting this vulnerability...

iLeakage: New Safari Exploit Impacts Apple iPhones and Macs with A- and M-Series CPUs

A group of academics has devised a novel side-channel attack dubbed iLeakage that exploits a weakness in the A- and M-series CPUs running on Apple iOS, iPadOS, and macOS devices, enabling the extraction of sensitive information from the Safari web browser. "An attacker can induce Safari to render...
