CVE-2026-82876 — Phison S11 SSD 固件签名验证绕过（PoC） 针对 CVE-2026-82876 （CVSS 3.1：8.2 高危 / CVSS 4.0：9.3 严重，CWE-347）的概念验证：Phison PS3111-S11 SATA SSD 控制器在验证固件更新 RSA 签名时，使用的是固件镜像自身内部嵌入的公共模数 ，而非锚定在不可变控制器存储中的模数。任何人都可以生成自己的 RSA 密钥对，对修改后的固件重新签名，嵌入匹配的模数——所有基于 S11 的驱动器都会将篡改后的镜像视为正品。 配套公告：CVE-2026-84696...

CVE-2026-76852

Netcore NR268 firmware version 1.7.121109 has an improper integrity verification flaw in mtdwrite allowing forged firmware authenticity checks. Attackers can exploit putfile.cgi and checkimageuuid.c to bypass firmware signature validation and load unauthorized firmware images...

CVE-2026-82876 Phison PS3111-S11 Controller Firmware Signature Verification Bypass

Phison PS3111-S11 controller firmware verifies RSA signatures using a public modulus embedded within the firmware image itself rather than anchored in immutable storage. Attackers can generate arbitrary RSA key pairs, sign modified firmware with the private key, embed the matching modulus in the...
