The US Cybersecurity and Infrastructure Security Agency (CISA) has warned that flaws in several Samsung mobile devices have likely already been exploited to by a spyware vendor.

The agency recently added eight new vulnerabilities to its Known Exploited Vulnerabilities Catalog, six of which pertain to Samsung Mobile devices, with evidence that they already been exploited in the wild.

Despite all these flaws having been patched by Samsung in 2021, there was no word from the Korean firm on the new revelations from CISA that they have been exploited.   

Google joins the fight

The vulnerabilities include CVE-2021-25487, which can be exploited to execute arbitrary code, and was fixed by Samsung in October 2021, as well as CVE-2021-25371, which allows attackers to load arbitrary ELF files inside the DSP driver, and was patched in March 2021. 

Both were classified as moderate severity by the electronics giant, although the NVD did classify the former as high based on its CVSS score. 

Another vulnerability, tracked as CVE-2023-21492, was also brought to the public's attention by Samsung and CISA, which can allow a privileged local attacker to bypass the ASLR exploit mitigation technique. This was also patched by Samsung in May this year. 

However, researchers at Google, who discovered it, claim that it had been known since 2021. In November 2022, Google also found more evidence of exploitation by spyware vendors of vulnerabilities in Samsung mobile devices known since 2021. 

It seems that CISA and Google have been tracking the same spyware vendors, and emphasizes the importance of patching software as soon as possible to avoid succumbing to malicious attacks and malware.

It isn't just Samsung devices that have been targets for threat actors recently, but rather Android devices on the whole. For instance, fake and dangerous apps on the Google Play Store appear to be getting increasingly popular, claiming more and more victims. 

To further protect your smart device, you can use the the best Android antivirus apps, or, if you're really concerned about maintaining your privacy as well as your security, you may want to consider getting one the best secure smartphones.
