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 (http://nvd.nist.gov/) (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 (http://cve.mitre.org/) 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 (https://www.incibe.es/enfeed/vulnerabilities) or Newsletters (https://www.incibe.es/encert/simplenews/subscriptions/landing) 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-2021-46947

Publication date:
27/02/2024
In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> sfc: adjust efx-&gt;xdp_tx_queue_count with the real number of initialized queues<br /> <br /> efx-&gt;xdp_tx_queue_count is initially initialized to num_possible_cpus() and is<br /> later used to allocate and traverse efx-&gt;xdp_tx_queues lookup array. However,<br /> we may end up not initializing all the array slots with real queues during<br /> probing. This results, for example, in a NULL pointer dereference, when running<br /> "# ethtool -S ", similar to below<br /> <br /> [2570283.664955][T4126959] BUG: kernel NULL pointer dereference, address: 00000000000000f8<br /> [2570283.681283][T4126959] #PF: supervisor read access in kernel mode<br /> [2570283.695678][T4126959] #PF: error_code(0x0000) - not-present page<br /> [2570283.710013][T4126959] PGD 0 P4D 0<br /> [2570283.721649][T4126959] Oops: 0000 [#1] SMP PTI<br /> [2570283.734108][T4126959] CPU: 23 PID: 4126959 Comm: ethtool Tainted: G O 5.10.20-cloudflare-2021.3.1 #1<br /> [2570283.752641][T4126959] Hardware name: <br /> [2570283.781408][T4126959] RIP: 0010:efx_ethtool_get_stats+0x2ca/0x330 [sfc]<br /> [2570283.796073][T4126959] Code: 00 85 c0 74 39 48 8b 95 a8 0f 00 00 48 85 d2 74 2d 31 c0 eb 07 48 8b 95 a8 0f 00 00 48 63 c8 49 83 c4 08 83 c0 01 48 8b 14 ca 8b 92 f8 00 00 00 49 89 54 24 f8 39 85 a0 0f 00 00 77 d7 48 8b<br /> [2570283.831259][T4126959] RSP: 0018:ffffb79a77657ce8 EFLAGS: 00010202<br /> [2570283.845121][T4126959] RAX: 0000000000000019 RBX: ffffb799cd0c9280 RCX: 0000000000000018<br /> [2570283.860872][T4126959] RDX: 0000000000000000 RSI: ffff96dd970ce000 RDI: 0000000000000005<br /> [2570283.876525][T4126959] RBP: ffff96dd86f0a000 R08: ffff96dd970ce480 R09: 000000000000005f<br /> [2570283.892014][T4126959] R10: ffffb799cd0c9fff R11: ffffb799cd0c9000 R12: ffffb799cd0c94f8<br /> [2570283.907406][T4126959] R13: ffffffffc11b1090 R14: ffff96dd970ce000 R15: ffffffffc11cd66c<br /> [2570283.922705][T4126959] FS: 00007fa7723f8740(0000) GS:ffff96f51fac0000(0000) knlGS:0000000000000000<br /> [2570283.938848][T4126959] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033<br /> [2570283.952524][T4126959] CR2: 00000000000000f8 CR3: 0000001a73e6e006 CR4: 00000000007706e0<br /> [2570283.967529][T4126959] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000<br /> [2570283.982400][T4126959] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400<br /> [2570283.997308][T4126959] PKRU: 55555554<br /> [2570284.007649][T4126959] Call Trace:<br /> [2570284.017598][T4126959] dev_ethtool+0x1832/0x2830<br /> <br /> Fix this by adjusting efx-&gt;xdp_tx_queue_count after probing to reflect the true<br /> value of initialized slots in efx-&gt;xdp_tx_queues.
