Out-of-bounds write via integer overflow in Android NFC stack enables RCE
CVE-2026-49879 is an integer overflow in Android's NFC reader/writer code (rw_t3t.cc, the component that handles NFC Type 3/FeliCa tags) that results in an out-of-bounds write when the stack processes crafted tag data. An attacker can trigger it by getting the device to process malicious NFC data — most plausibly a nearby malicious NFC tag — with no user interaction and no special privileges required. Successful exploitation yields remote code execution in the context of the NFC service, though no public proof-of-concept or in-the-wild exploitation is currently known. Any Android device with NFC hardware is potentially affected, with the fix delivered through the September 2026 Android Security Update. EPSS currently estimates only a 0.2% probability of exploitation within 30 days and the flaw is not yet in CISA's KEV catalog.

Remote DoS/RCE in Android image resolver via DNG rendering check bypass
CVE-2026-28666 is a flaw in LocalImageResolver.java in the Android platform's image-handling code, where a DNG (Digital Negative) image rendering check can be bypassed. The Android security team classifies the issue as a remote persistent denial of service, but notes it could also lead to remote escalation of privilege, requiring no additional execution privileges and no user interaction. An attacker could trigger the flaw by getting a crafted DNG image processed by an affected device, degrading the device persistently or, per the bulletin, gaining elevated code execution. The flaw affects the Android platform component (assigned by
[email protected]), so any Android device shipping the vulnerable image-resolution code is potentially exposed, pending OEM patches. There is currently no public proof-of-concept, the flaw is not in CISA's KEV catalog, and EPSS estimates only a 0.2% probability of exploitation in the next 30 days.

Heap Buffer Overflow in Android Wi-Fi Direct (P2P) Provisioning Discovery Enables Nearby RCE
CVE-2026-28662 is a heap buffer overflow causing an out-of-bounds write in p2p_process_prov_disc_bootstrap_req in p2p_pd.c, the code that handles Wi-Fi P2P (Wi-Fi Direct) provisioning discovery bootstrap requests in Android's Wi-Fi stack. It is triggered when a nearby attacker sends a crafted bootstrap request over the air while the device's Wi-Fi is enabled; no user interaction or privileges are required. Successful exploitation yields remote (proximal/adjacent) code execution, meaning anyone within Wi-Fi radio range could run code on the device. Android devices running software prior to the September 2026 Android Security Update are affected. Exploitation is not currently observed: there is no public proof-of-concept, it is not in CISA's KEV, and EPSS puts 30-day exploitation probability at about 0.1%.

CVE-2026-58846 is a use-after-free in the kvm_iommu_map_sg function (iommu.c) of the KVM IOMMU code in the Android Linux kernel, caused by a missing permission check (CWE-269). A local attacker can reach the vulnerable scatter-gather mapping path and trigger the flaw without user interaction and with no additional execution privileges. Successful exploitation yields local escalation of privilege with high impact on confidentiality, integrity, and availability (CVSS 3.1: 7.8). Affected parties are users of Android devices running vulnerable kernel builds; Google shipped the fix in the September 2026 Android Security Update. There is no public proof-of-concept, the flaw is not in CISA's KEV, and EPSS estimates only a 0.1% probability of exploitation within 30 days, so no exploitation is currently known.

Out-of-Bounds Write in Android NFC (MIFARE Classic) Allows Local Privilege Escalation
CVE-2026-28639 is an out-of-bounds write in rw_mfc_handle_read_op (rw_mfc.cc), the handler for MIFARE Classic tag read operations in the Android NFC stack, caused by a logic error in the code. It is triggered when the NFC subsystem processes MIFARE Classic read operations, and exploitation requires no user interaction and no additional execution privileges. A successful exploit corrupts adjacent memory and can lead to local escalation of privilege on the affected device. All Android devices running the vulnerable NFC code are affected; the flaw is addressed in the September 2026 Android Security Update. There is currently no public proof of concept, the issue is not in CISA KEV, and EPSS puts 30-day exploitation probability at roughly 0.1%, so no exploitation is known.

Improper Encryption Key Validation Enables Local Privilege Escalation in Android
CVE-2026-28590 is a local privilege escalation flaw in Android caused by a logic error that results in improper validation of encryption keys in multiple places in the code. It is triggered by code already running locally on the device, with no need for special execution privileges and no user interaction, so any app or process with local code execution could potentially exploit it. An attacker who exploits it gains elevated privileges on the affected device, which is most valuable as one link in a chained attack alongside other flaws (the September 2026 Android bulletin also fixed separate remote code execution issues). Affected parties are users of Android devices that have not yet received the September 2026 Android security update; the specific affected version ranges were not detailed in the available data. There is no known public proof of concept, it is not listed in CISA's Known Exploited Vulnerabilities catalog, and its current probability of exploitation within 30 days is estimated at 0.1%.
