Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from a typo in the acpipccretrievebiosdata function, which allows for out-of-bounds writing to the pcc-sinf array, potentially leading to a stack overflow...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.14 contains a security vulnerability. This vulnerability arises from the use of qnapmcuexec, which exposes the stack-based receive buffer to the unsynchronized serdev receive path. In cases where commands fail or writes fail, delayed responses or unrequested messages ma...

vim: Vim: Denial of Service via crafted spell file

A flaw was found in Vim, an open-source command-line text editor. A remote attacker could exploit this vulnerability by convincing a user to load a specially crafted spell file. This malicious file can trigger a stack out-of-bounds write, which corrupts the editor's memory and causes it to crash...

apr-util: Apache Portable Runtime Utility: Denial of Service via XML stack recursion attack

A flaw was found in Apache Portable Runtime Utility apr-util. A remote attacker could exploit a stack recursion vulnerability by providing specially crafted XML input to a library consumer that uses the aprxmlquoteelem function. This could lead to a denial of service DoS due to an application cra...

encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...
