CVE-2026-863586.5 MED—
———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.3hCVE-2026-768697.2 ALT—
———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.23hCVE-2026-768618.8 ALT—
———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.23hCVE-2026-768608.8 ALT—
———Netcore NR255-V version 1.5.130703 contains a stack-based buffer overflow in wake_up_set.cgi caused by unbounded tokenization of MAC and ID input. Attackers can supply crafted MAC and ID values to the affected endpoint to overflow the stack buffer and corrupt program memory.23hCVE-2026-197747.1 ALT—
———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-29429.17hCVE-2026-918264.4 MED1.5%
——0Stack-based buffer overflow vulnerability in Samsung Opensource rLottie allows attackers to overflow buffers, leading to memory corruption when rendering crafted vector animations.
