Exploited in the wild (CISA KEV). Memory corruption while maintaining memory maps of HLOS memory.
CISA KEV · added 2024-10-08 CVSS 7.8 High EPSS 0.7% · p51
Should you act?
Exploited: patch now if you run it
CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Yes, if you run Qualcomm Multiple Chipsets. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-10-08, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-10-29; treat that as the outer limit, not the target.
- EPSS 0.7%, percentile 51: FIRST’s model estimates a 0.7% chance of exploitation activity in the next 30 days, higher than 51% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
What it is
