CVE-2026-6685

CVE-2026-6685 refers to an Integer Underflow in FatFs during dirty-sector cache flush when handling fragmented volumes. Affected software is FatFs R0.16 and earlier; the issue arises from an unsigned-subtraction wrap in cache handling (fp->sect vs. sect) during interleaved read/write, which ca...

php: ext/openssl: memory corruption in openssl_encrypt with AES-WRAP-PAD

A flaw was found in the OpenSSL extension of PHP. The AES-WRAP-PAD algorithm implementation uses the size of the plaintext length without accounting for the RFC 5649 expansion to allocate the output buffer for the AES key-wrap-with-padding operation. This may lead to an undersized memory allocati...
