RIOT OS Buffer Error Vulnerability

RIOT OS versions before 2026.04 have a buffer error vulnerability. This vulnerability stems from the atwinc15x0stasetcurrentssid function in the ATWINC15x0 driver, which uses strcpy to copy an SSID without checking the target size. When MODULEATWINC15X0DYNAMICCONNECT is enabled, nearby attackers...

RIOT OS Digital Error Vulnerability

Versions of Riot OS prior to 2026.07 contain security vulnerabilities. These vulnerabilities stem from nanocoap not enforcing a 20-bit maximum block number limit for the extremely large CoAP Block2 option values. This allows for overflow during block offset multiplication on 32-bit targets,...

RIOT OS Buffer Error Vulnerability

RIOT OS versions before 2026.07 have security vulnerabilities. These vulnerabilities stem from the parsereply function in sys/net/applicationlayer/dhcpv6/client.c. This function fails to perform a minimum length validation before passing the IAPD and IANA option bodies to the sub-option parser...
