The vulnerability of the handle_misaligned_load() function in the arch/riscv/kernel/traps_misaligned.c module of the module management subsystem for the RISC-V architecture-based Linux operating system allows a attacker to access protected information.

The vulnerability of the handlemisalignedload function in the arch/riscv/kernel/trapsmisaligned.c module of the module management subsystem for the RISC-V architecture-based Linux operating system is related to access control deficiencies. Exploiting this vulnerability could allow an attacker to...

Metasploit Wrap-Up 11/28/2025

This week, we have added 10 new modules to Metasploit Framework including an SMB to MSSQL relay module, a remote code execution module targeting Fortinet software, additional 32-bit and 64-bit RISC-V payloads, and more. The SMB to MSSQL NTLM relay module allows users to open MSSQL sessions and ru...

The vulnerability of the ipi_remote_fence_i() function in the arch/riscv/mm/cacheflush.c module on RISC-V architecture processors in the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the ipiremotefencei function in the arch/riscv/mm/cacheflush.c module on RISC-V architecture processors in Linux operating systems is related to improper resource management. Exploiting this vulnerability could allow an attacker to cause a service failure...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: RISC-V: KVM: A stack overflow issue was fixed when loading vlenb. The user-space load mechanism can place up to 2048 bits into the xlen bit stack buffer. Since we only need the xlen bits, we check the size of the buffer in advanc...

USN-7833-4: Linux kernel (GCP) vulnerabilities

Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Köpf, Stavros Volos, and Flavien Solt discovered that some AMD processors may allow an attacker to infer data from previous stores, potentially resulting in the leakage of privileged information. A local attacker could possibly use this to...
