Optimizing Scalar Selection in Elliptic Curve Cryptography Using Differential Evolution for Enhanced Security

Elliptic Curve Cryptography ECC is a fundamental component of modern public-key cryptosystems that enable efficient and secure digital signatures, key exchanges, and encryption. Its core operation, scalar multiplication, denoted as $k \cdot P$, where $P$ is a base point and $k$ is a private scala...

CVE-2025-5918

A vulnerability has been identified in the libarchive library. This flaw can be triggered when file streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-bounds read can lead to unintended consequences, including unpredictable program behavior, memo...

CVE-2025-5915 Libarchive: heap buffer over read in copy_from_lzss_window() at archive_read_support_format_rar.c

A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber LZSS window. This means the library may attempt to read beyond the allocated memory buffer, which can...

Azure Linux 3.0 Security Update: kernel (CVE-2025-21919)

The version of kernel installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-21919 advisory. - In the Linux kernel, the following vulnerability has been resolved: sched/fair: Fix potential memory...

CVE-2025-21919

CVE-2025-21919 (Linux kernel sched/fair): A memory-corruption issue was fixed in child_cfs_rq_on_list. The prev pointer used in converting to a cfs_rq could originate from rq->leaf_cfs_rq_list, making container_of incorrect and risking memory fault or garbage reads. The patch adds a guard: aft...

CVE-2025-21919 sched/fair: Fix potential memory corruption in child_cfs_rq_on_list

In the Linux kernel, the following vulnerability has been resolved: sched/fair: Fix potential memory corruption in childcfsrqonlist childcfsrqonlist attempts to convert a 'prev' pointer to a cfsrq. This 'prev' pointer can originate from struct rq's leafcfsrqlist, making the conversion invalid and...

GHSA-H33Q-MHMP-8P67 Vyper has a double eval in For List Iter

Multiple evaluation of a single expression is possible in the iterator target of a for loop. While the iterator expression cannot produce multiple writes, it can consume side effects produced in the loop body e.g. read a storage variable updated in the loop body and thus lead to unexpected progra...

CVE-2024-7558

JUJUCONTEXTID is a predictable authentication secret. On a Juju machine non-Kubernetes or Juju charm container on Kubernetes, an unprivileged user in the same network namespace can connect to an abstract domain socket and guess the JUJUCONTEXTID value. This gives the unprivileged user access to t...
