CVE-2023-2007 – Linux Kernel DPT I2O Controller Time-Of-Check Time-Of-Use Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2023-2007
The specific flaw exists within the DPT I2O Controller driver. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel. This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DPT I2O Controller driver. • https://github.com/torvalds/linux/commit/b04e75a4a8a81887386a0d2dbf605a48e779d2a0 https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://security.netapp.com/advisory/ntap-20240119-0011 https://www.debian.org/security/2023/dsa-5480 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-667: Improper Locking •

CVE-2022-36879 – kernel: xfrm_expand_policies() in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice
https://notcve.org/view.php?id=CVE-2022-36879
An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.14. la función xfrm_expand_policies en el archivo net/xfrm/xfrm_policy.c puede causar que un refcount sea descartado dos veces A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). An error while resolving policies in xfrm_bundle_lookup causes the refcount to drop twice, leading to a possible crash and a denial of service. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=f85daf0e725358be78dfd208dea5fd665d8cb901 https://github.com/torvalds/linux/commit/f85daf0e725358be78dfd208dea5fd665d8cb901 https://lists.debian.org/debian-lts-announce/2022/09/msg00011.html https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security.netapp.com/advisory/ntap-20220901-0007 https://www.debian.org/security/2022/dsa-5207 https://access.redhat.com/security/cve/CVE-2022-36879 https://bugzilla.r • CWE-911: Improper Update of Reference Count •
CVE-2022-2068 – The c_rehash script allows command injection
https://notcve.org/view.php?id=CVE-2022-2068
In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other places in the script where the file names of certificates being hashed were possibly passed to a command executed through the shell. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. • https://cert-portal.siemens.com/productcert/pdf/ssa-332410.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2c9c35870601b4a44d86ddbf512b38df38285cfa https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=7a9c027159fe9e1bbc2cd38a8a2914bff0d5abd9 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=9639817dac8bbbaa64d09efad7464ccc405527c7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6WZZBKUHQFGSKGNXXKICSRPL7AMVW5M5 https://lists.fedoraproject.org/archives/list • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
