VU#369611: ExLlamaV3 contains Denial of Service vulnerability via insufficient bounds checking on kernel dispatch index
CERT/CC details CVE-2026-84286, an out-of-bounds memory access in ExLlamaV3's CUDA extension causing denial-of-service crashes; fixed via merged pull request.
CERT/CC published VU#369611 for CVE-2026-84286, an out-of-bounds memory access in the exllamav3_ext CUDA extension of the ExLlamaV3 LLM inference library. A crafted input with kernel parameter K set to 0 produces a negative index into a fixed 24-entry kernel dispatch array, causing a CUDA illegal memory access and denial-of-service crashes. The vendor fixed the issue in the main repository via pull request #310, and maintainers of 49 downstream projects, including ezexl3 and MawDiscord, are advised to rebuild against the patched version. The issue was reported by Nathan Keys and impact is limited to crashes and instability, not code execution.

Microsoft Excel KB5002914 update breaks copy and paste for some users
Microsoft's September Patch Tuesday update KB5002914 breaks copy-and-paste and formula dragging in Excel 2016 through 2024; uninstalling the update restores functionality.
Users on Reddit and Microsoft Q&A report that the KB5002914 security update shipped in the September 2026 Patch Tuesday breaks copy-and-paste, autofill, and formula dragging in Excel. The problem spans Office 2016 through 2024 across MSI and Click-to-Run installations, including Office LTSC Standard 2021, with some teams blocked after widespread patching. Uninstalling KB5002914 or downgrading the Office build restores functionality, though replacing the excel.exe binary is not recommended. BleepingComputer could not reproduce the issue on Excel 2019 Version 2508 Build 19127.20302 and contacted Microsoft for comment.

VU#859658: Skullcandy Dime 3 wireless earbuds contain an unauthenticated Bluetooth pairing vulnerability
Skullcandy Dime 3 earbuds (CVE-2025-20701) accept Bluetooth pairings without owner consent, letting in-range attackers hijack audio or capture microphone; no firmware update path exists.
CERT/CC's VU#859658 describes CVE-2025-20701 in the Airoha Bluetooth audio SDK, present in Skullcandy Dime 3 (Model S2DCW) firmware 1.0.0.28. A direct Bluetooth Classic pairing request with no PIN or physical confirmation completes via NoInputNoOutput, adding the attacker's device as trusted. Attackers in radio range can hijack the A2DP audio session, access the Hands-Free/Headset profile, and capture live microphone audio. Firmware 1.0.0.30 contains the effective patch, but Skullcandy says the Dime 3 does not support app-based firmware updates, leaving existing units unpatchable.

3 Vulnerabilities Found on AvertX IP Cameras
Unit 42 disclosed three vulnerabilities (CVE-2020-11623/4/5) in AvertX HD838 and 438IR IP cameras; AvertX has released patches.
Palo Alto Networks Unit 42 researchers found three vulnerabilities in AvertX HD838 and 438IR outdoor surveillance cameras, which are rebranded Hikvision products: CVE-2020-11625 (user enumeration), CVE-2020-11624 (weak password requirements), and CVE-2020-11623 (exposed dangerous method/function). User enumeration responses facilitate brute-force attacks, the default admin credentials (admin/1234) are never enforced to change, and physical access to an exposed UART interface allows bootloader access and configuration modification. AvertX released a patch, removed the UART connector, and disabled the interface in the latest production batch.
