What is CVE-2026-24110?
CVE-2026-24110 is a critical memory corruption vulnerability in n/a, published on 2 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may send overly long `addDhcpRules` data. When these rules enter the `addDhcpRule` function and are processed by `ret = sscanf(pRule, " %d\t%[^\t]\t%[^\n\r\t]", &dhcpsIndex, dhcpsIP, dhcpsMac);`, the lack of size validation for the rules could lead to buffer overflows in `dhcpsIndex`, `dhcpsIP`, and `dhcpsMac`.
