Dword XOR Encoder (Tag-based)

Dword XOR encoder for RISC-V 32-bit Little Endian using a tag-based terminator rather than an encoded length. The decoder loop XORs each dword and stops when the result is zero the sentinel. This avoids encoding the payload length in the stub, eliminating a source of bad character conflicts. Note...

USN-8527-1 linux-raspi vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - RISC-V architecture; - Cryptographic API; - InfiniBand drivers; - IOMMU subsystem; - Network drivers; -...

The vulnerability of the copy_thread() function in the arch/riscv/kernel/process.c module of the kernel subsystem of the Linux operating system’s RISCV architecture-based platform allows a malicious actor to gain unauthorized access to protected information or cause service failures.

The vulnerability of the copythread function in the arch/riscv/kernel/process.c module of the Linux operating system’s RISCV architecture-based kernel subsystem involves the disclosure of confidential information. Exploiting this vulnerability could allow an attacker to gain unauthorized access t...

CVE-2026-53351

CVE-2026-53351 affects the Linux kernel in the riscv/ptrace path, where the REGSET_CFI handling now uses USER_REGSET_NOTE_TYPE. The authenticated change resolves a core-dump warning seen as a note in fs/binfmt_elf.c during elf_core_dump, CPU#7. The available connected records corroborate that thi...
