CVE-2026-76861 2026-09-21 N/A 8.8 HIGH
Netcore NR255-V version 1.5.130703 contains a stack-based buffer overflow in ntools_tcpdump_start_set.cgi caused by an unsized sprintf call when processing form values. An attacker can submit crafted input to this cgi endpoint to overflow the stack buffer and potentially execute arbitrary code.
CVE-2026-86358 1 Dell 1 Update Package Framework 2026-09-21 N/A 6.5 MEDIUM
Dell Update Package Framework, versions prior to 26.07.03, contains a Stack-based Buffer Overflow vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Remote execution.
CVE-2026-93372 1 Google 2 Android, Chrome 2026-09-21 N/A 9.6 CRITICAL
Buffer overflow in WebGL in Google Chrome on on Android prior to 153.0.8010.52 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical)
CVE-2026-91843 2026-09-18 N/A 9.8 CRITICAL
A stack overflow during the unauthenticated login process may allow an attacker to run arbitrary code remotely with root privileges.
CVE-2026-91826 2026-09-18 N/A 4.4 MEDIUM
Stack-based buffer overflow vulnerability in Samsung Opensource rLottie allows attackers to overflow buffers, leading to memory corruption when rendering crafted vector animations. This issue affects rLottie: 480a2ad0c5d2e45458c545b8213279e9e8b71e39.
CVE-2026-90823 2026-09-18 N/A 9.8 CRITICAL
FatPipe MPVPN, WARP, and IPVPN appliances running the end-of-life firmware version 10.1.2r60p100 contain a stack-based buffer overflow in /usr/sbin/auth_user_pass. An unauthenticated remote attacker with access to the affected management interface can submit a crafted authentication request that reaches an unchecked copy into a fixed-size stack buffer, potentially allowing arbitrary code execution as root. The affected management interface is disabled by default and must be affirmatively enabled by the customer before the endpoint becomes reachable. FatPipe recommends restricting management access to trusted administrative networks and using WAN access control lists to limit access to trusted sources. Customers running the affected end-of-life firmware can contact FatPipe Support for help confirming their firmware version and upgrading to a current supported release at https://www.fatpipeinc.com/support/support, support@fatpipeinc.com, or +1 800-724-8521 (option 3).
CVE-2026-19774 2026-09-18 N/A 7.1 HIGH
BlueZ A2DP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability. The specific flaw exists within the handling of the stream endpoints. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-29429.
CVE-2026-19542 2026-09-18 N/A 5.6 MEDIUM
Calling tdelete on a sufficiently deep tree in the GNU C Library version 2.1 to 2.44 may write one pointer past the end of an alloca-allocated array on the stack, which may crash the application. The tdelete implementation keeps an explicit stack of parent nodes for rebalancing, which is grown as needed while descending the tree. Two rebalancing branches push an additional entry without checking the capacity, and write past the array when the stack is exactly full. Triggering this requires a node at a depth of exactly 40 (or 40 plus a multiple of 20), which implies a tree with at least a million nodes, so an attacker must drive a large number of insertions and deletions through an application that uses tsearch and tdelete. The written value is a pointer into a tree node and is not directly attacker controlled. No affected application in common distributions has been identified.
CVE-2026-81546 2026-09-18 N/A 7.7 HIGH
The Affinity by Canva application before 3.3.0 (September 2026 release) did not perform adequate bounds checking when parsing Affinity document files leading to a stack-based buffer overflow. A threat actor could craft a Affinity document that when opened by a user in Affinity could result in arbitrary code execution.

CVE-2026-76869 2026-09-17 N/A 7.2 HIGH
Netcore NR255-V version 1.5.130703 contains a stack-based buffer overflow in reboot_timer_set.cgi caused by improper sscanf token parsing. Attackers can exploit this flaw by submitting crafted input to the affected endpoint to corrupt stack memory.
CVE-2026-69759 1 Microsoft 6 365 Apps, Microsoft 365, Office 2019 and 3 more 2026-09-17 N/A 8.8 HIGH
