Oracle-mysql-CVE-2012-2122
MySQL Authentication Bypass Vulnerability CVE-2012-2122 When connecting to MariaDB/MySQL, the entered password is compared with the expected correct password. Due to improper handling, even if memcmp returns a non-zero value, MySQL may still consider the two passwords as identical. That is, as lo...
CVE-2026-55606
odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. In versions 25.12 and prior, odhcpd's DHCPv6 self-loop detection at dhcpv6.c:720 uses a network-byte-order DUID length value directly as the memcmp size parameter. On little-endian hosts, this causes memcmp to read far...
CVE-2026-55606
The odhcpd server, used by OpenWrt in versions 25.12 and prior , is vulnerable to a stack buffer overread due to a DUID length endianness mismatch in dhcpv6.c:720. On little-endian hosts , the software uses a network-byte-order DUID length value directly as a memcmp() size parameter, allowing a s...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: mtd: Avoid boot crashes in the RedBoot partition table parser Given the CONFIGFORTIFYSOURCE=y configuration and a recent compiler version, the commit 439a1bcac648 “fortify: Use builtindynamicobjectsize when available” results in...
Astra Linux – Vulnerability in Heimdal
The fix for CVE-2022-3437 involved changing the memcmp function to run in constant time, as well as providing a workaround for a compiler bug by adding comparisons of the result with the value “!= 0” to the memcmp function. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0...
BIT-PHP-MIN-2026-91768 IPv6 ACL bypass in FastCGI listen.allowed_clients due to partial address comparison (memcmp 12 bytes)
The IPv6 branch of the FastCGI client access check compares only the first 12 bytes of a 16-byte IPv6 address, so listen.allowedclients matches on a /96 prefix instead of the exact address. An attacker who can source an address sharing the first 96 bits with an allowed one passes the check and...

glib: buffer over-read in glib/giochannel.c via "g_io_channel_read_line_backend"
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 ...
