Vulnerabilities

With the aim of informing, warning and helping professionals with the latest security vulnerabilities in technology systems, we have made a database available for users interested in this information, which is in Spanish and includes all of the latest documented and recognised vulnerabilities.

This repository, with over 75,000 registers, is based on the information from the NVD (National Vulnerability Database) – by virtue of a partnership agreement – through which INCIBE translates the included information into Spanish.

On occasions this list will show vulnerabilities that have still not been translated, as they are added while the INCIBE team is still carrying out the translation process. The CVE  (Common Vulnerabilities and Exposures) Standard for Information Security Vulnerability Names is used with the aim to support the exchange of information between different tools and databases.

All vulnerabilities collected are linked to different information sources, as well as available patches or solutions provided by manufacturers and developers. It is possible to carry out advanced searches, as there is the option to select different criteria to narrow down the results, some examples being vulnerability types, manufacturers and impact levels, among others.

Through RSS feeds or Newsletters we can be informed daily about the latest vulnerabilities added to the repository. Below there is a list, updated daily, where you can discover the latest vulnerabilities.

CVE-2024-46701

Publication date:
13/09/2024
In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> libfs: fix infinite directory reads for offset dir<br /> <br /> After we switch tmpfs dir operations from simple_dir_operations to<br /> simple_offset_dir_operations, every rename happened will fill new dentry<br /> to dest dir&amp;#39;s maple tree(&amp;SHMEM_I(inode)-&gt;dir_offsets-&gt;mt) with a free<br /> key starting with octx-&gt;newx_offset, and then set newx_offset equals to<br /> free key + 1. This will lead to infinite readdir combine with rename<br /> happened at the same time, which fail generic/736 in xfstests(detail show<br /> as below).<br /> <br /> 1. create 5000 files(1 2 3...) under one dir<br /> 2. call readdir(man 3 readdir) once, and get one entry<br /> 3. rename(entry, "TEMPFILE"), then rename("TEMPFILE", entry)<br /> 4. loop 2~3, until readdir return nothing or we loop too many<br /> times(tmpfs break test with the second condition)<br /> <br /> We choose the same logic what commit 9b378f6ad48cf ("btrfs: fix infinite<br /> directory reads") to fix it, record the last_index when we open dir, and<br /> do not emit the entry which index &gt;= last_index. The file-&gt;private_data<br /> now used in offset dir can use directly to do this, and we also update<br /> the last_index when we llseek the dir file.<br /> <br /> [brauner: only update last_index after seek when offset is zero like Jan suggested]
