CVE-2020-26146: An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices.

MediumCVSS 5.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 23/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 5.6% (FIRST EPSS); higher than 93% of all records.
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: kernel-tools-libs-devel (AlmaLinux:8) 4.18.0-348.el8; bpftool (Red Hat:enterprise_linux:8::baseos) 0:4.18.0-348.el8; bpftool-debuginfo (Red Hat:enterprise_linux:8::baseos) 0:4.18.0-348.el8.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to kernel-tools-libs-devel (AlmaLinux:8) 4.18.0-348.el8; bpftool (Red Hat:enterprise_linux:8::baseos) 0:4.18.0-348.el8; bpftool-debuginfo (Red Hat:enterprise_linux:8::baseos) 0:4.18.0-348.el8 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by design.
