CVE-2026-74521 ksmbd: use memcmp() to compare ClientGUIDs

In the Linux kernel, the following vulnerability has been resolved: ksmbd: use memcmp to compare ClientGUIDs ClientGUID is a fixed-size binary value and can contain embedded NUL bytes. strncmp stops comparing at the first NUL byte, so different ClientGUID values can incorrectly be treated as equa...

CVE-2026-74521

The CVE-2026-74521 vulnerability affects the Linux kernel’s ksmbd component, where ClientGUIDs were compared with strncmp() and could misclassify distinct GUIDs that contain embedded NUL bytes. The fix uses memcmp() to compare all SMB2_CLIENT_GUID_SIZE bytes in SMB3 multichannel session binding a...

CVE-2026-56391: Out-of-bounds Read

GNU coreutils uniq is vulnerable to an out‑of‑bounds read due to incorrect handling of multibyte input when the -w --check-chars option is used. The findfield function miscalculates the byte length of characters by repeatedly processing a fixed pointer instead of advancing through the input,...

CVE-2026-15041: Observable Timing Discrepancy

A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash...

CVE-2026-41514: Observable Timing Discrepancy

OP-TEE is a Trusted Execution Environment TEE designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 4.5.0 and prior to version 4.11.0, the RSA-OAEP decryption implementation in the Hisilicon HPRE crypto driver uses...

CVE-2026-58013

A flaw was found in GLib. A buffer over-read can occur in giochannelreadlinebackend in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes ...
