CVE-2019-15126: An issue was discovered on Broadcom Wi-Fi client devices.
Noroxi assessment
Priority: Monitor (action score 14/100)
- Public proof-of-concept code exists (Exploit-DB, GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 7.2% (FIRST EPSS); higher than 94.3% 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-firmware (openSUSE:Leap 15.2) 20200107-lp152.2.9.1; kernel-debug (openSUSE:Leap 15.3) 4.12.14-197.105.1; kernel-default (openSUSE:Leap 15.3) 4.12.14-197.105.1.
- Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to kernel-firmware (openSUSE:Leap 15.2) 20200107-lp152.2.9.1; kernel-debug (openSUSE:Leap 15.3) 4.12.14-197.105.1; kernel-default (openSUSE:Leap 15.3) 4.12.14-197.105.1 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 Broadcom Wi-Fi client devices. Specifically timed and handcrafted traffic can cause internal errors (related to state transitions) in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure over the air for a discrete set of traffic, a different vulnerability than CVE-2019-9500, CVE-2019-9501, CVE-2019-9502, and CVE-2019-9503.

No credits in the CNA record.
Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
