crypto/internal/nistec: golang: Timing sidechannel for P-256 on ppc64le in crypto/internal/nistec

A flaw was found in the Golang crypto/internal/nistec package. Due to the usage of a variable time instruction in the assembly implementation of an internal function, a small number of bits of secret scalars are leaked on the ppc64le architecture. Considering how this function is used, this leaka...

kernel: secretmem: disable memfd_secret() if arch cannot set direct map

A flaw was found in the Linux kernel. On certain ARM64 systems, the memfdsecret system call, intended to create secure memory regions, may appear to function correctly but fails to remove the memory from the direct map. This silent failure means that memory designated as secret is not properly...

kernel: s390/vmem: split pages when debug pagealloc is enabled

In the Linux kernel’s s390/vmem subsystem, a flaw exists in the handling of virtual memory area initialization when debug pagealloc is enabled. Under certain conditions, the kernel may access memory after it has been freed or mishandled during early boot or subsystem initialization, resulting in ...

kernel: s390/idle: mark arch_cpu_idle() noinstr

A kernel warning vulnerability was found in the s390 architecture idle handling in the Linux kernel. The archcpuidle function was not marked as noinstr no instrumentation, causing RCU and tracing warnings when ftrace is enabled. This can trigger kernel warnings and potential issues with tracing i...

kernel: platform/x86: ISST: Fix the KASAN report slab-out-of-bounds bug

A flaw was found in the Linux kernel. A local attacker with privileges to manage virtual machines could exploit this vulnerability by attaching a specific Intel Speed Select Technology ISST PCI device to a virtual machine. This action triggers a memory error known as a slab-out-of-bounds, which c...

kernel: amba: bus: fix refcount leak

A reference count leak was found in the ARM AMBA bus driver. When AMBA devices are created from device tree, the ofnode reference count is incremented but never decremented in ambadevicerelease, causing gradual memory leaks...

kernel: s390: avoid using global register for current_stack_pointer

In the Linux kernel, the following vulnerability has been resolved: s390: avoid using global register for currentstackpointer Commit 30de14b1884b "s390: currentstackpointer shouldn't be a function" made currentstackpointer a global register variable like on many other architectures. Unfortunately...

kernel: Linux kernel (s390): Denial of service and data corruption due to improper page table updates

A flaw was found in the Linux kernel on the s390 architecture. A local user with low privileges could trigger a vulnerability by enabling ARCHWANTOPTIMIZEHUGETLBVMEMMAP. This issue arises because kernel page table entries are modified without properly flushing the Translation Lookaside Buffer TLB...

kernel: s390/dcssblk: fix kernel crash with list_add corruption

A kernel crash vulnerability was found in the Linux kernel's s390 dcssblk driver. Missing daxremovehost calls in the device removal path, combined with broken error handling in the device add path, cause stale xarray entries and listadd corruption. When a previously used gendisk pointer is reused...

Blockchain Technology: Core Mechanisms, Evolution, and Future Implementation Challenges

Blockchain technology has emerged as one of the most transformative digital innovations of the 21st century. This paper presents a comprehensive review of blockchain's fundamental architecture, tracing its development from Bitcoin's initial implementation to current enterprise applications. We...

ALSA-2025:7409 Moderate: git security update

Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to wo...

Unbreakable Enterprise kernel security update
