CVE-2026-76920 Out-of-bounds Write in Wireshark

3gpp phone log file parser crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service...

CVE-2026-76920

Wireshark versions 4.6.0–4.6.7 and 4.4.0–4.4.18 contain an out-of-bounds write in the 3GPP phone log file parser, triggered by a crafted log file, causing a denial-of-service crash. CVSS 4.7 (Medium) requires local access and user interaction. No in-the-wild exploitation is reported; upgrade to a...

CVE-2026-76880 Out-of-bounds Write in Wireshark

CVE-2026-76880

Wireshark's RRC (Radio Resource Control) protocol dissector crashes in versions 4.6.0–4.6.7 and 4.4.0–4.4.18 when processing crafted network traffic, enabling remote denial of service (CVSS 7.5, HIGH). The crash is triggered without authentication. Upgrade to patched versions; see the WNP Sec adv...

CVE-2026-12634

The NVS backend of the Zephyr settings subsystem subsys/settings/src/settingsnvs.c reads stored setting-name entries into fixed 74-byte stack buffers and NUL-terminates them with bufrc = '\0', where rc is the return value of nvsread. Per its contract, nvsread returns the full stored entry length...

CVE-2026-12634 Out-of-bounds stack write in the settings NVS backend from over-reported nvs_read length

The NVS backend of the Zephyr settings subsystem subsys/settings/src/settingsnvs.c reads stored setting-name entries into fixed 74-byte stack buffers and NUL-terminates them with bufrc = '\0', where rc is the return value of nvsread. Per its contract, nvsread returns the full stored entry length...

CVE-2026-12633 Out-of-bounds write in IPv6 6LoWPAN Context Option handling via unauthenticated Router Advertisement

The IPv6 neighbor-discovery code in subsys/net/ip/ipv6nbr.c processes the 6LoWPAN Context Option 6CO, RFC 6775 carried inside ICMPv6 Router Advertisements. In handlera6co the 8-bit contextlen field is taken directly from the packet and was never bounded to the RFC maximum of 128. The function...
