CVE-2026-6104 2 Php, Php Group 2 Php, Php 2026-05-12 9.1 Critical
In PHP versions 8.4.* before 8.4.21 and 8.5.* before 8.5.6, when an encoding name containing an embedded NUL byte is passed to mb_convert_encoding() or related mbstring functions, the code incorrectly assumes that when strncasecmp() returns 0 it means the strings have the same length. This can lead to out-of-bounds read of global memory, potentially causing a crash or information disclosure or crash. Affected functions include mb_convert_encoding(), mb_detect_encoding(), mb_convert_variables(), and mb_detect_order(), as well as the mbstring.detect_order and mbstring.http_output INI settings.
CVE-2026-20751 2026-05-12 N/A
Out-of-bounds read for the Intel(R) Data Center Graphics Driver for VMware ESXi software before version 2.0.2 within Ring 1: Device Drivers may allow a denial of service. System software adversary with a privileged user combined with a low complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (none) and availability (high) impacts.
CVE-2026-20782 2026-05-12 N/A
Buffer overflow for some Intel(R) QAT software drivers for Windows before version 1.13 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
CVE-2026-20794 2026-05-12 N/A
Buffer overflow for the Intel(R) Data Center Graphics Driver for VMware ESXi software before version 2.0.2 within Ring 1: Device Drivers may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable local code execution. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (high) impacts.

CVE-2023-4911 7 Canonical, Debian, Fedoraproject and 4 more 51 Ubuntu Linux, Debian Linux, Fedora and 48 more 2026-05-12 7.8 High
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2026-31431 11 Amazon, Arista, Canonical and 8 more 43 Amazon Linux, Cloudvision Agni, Cloudvision Portal and 40 more 2026-05-12 7.8 High
In the Linux kernel, the following vulnerability has been resolved: crypto: algif_aead - Revert to operating out-of-place This mostly reverts commit 72548b093ee3 except for the copying of the associated data. There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly.
CVE-2026-28848 1 Apple 1 Macos 2026-05-12 7.5 High
A buffer overflow was addressed with improved bounds checking. This issue is fixed in macOS Sequoia 15.7.7, macOS Tahoe 26.5. A remote attacker may be able to cause unexpected system termination.
CVE-2026-45190 1 Stigtsp 1 Net::cidr::lite 2026-05-12 6.5 Medium
Net::CIDR::Lite versions before 0.24 for Perl does not properly validate IP address and CIDR mask inputs, which may allow IP ACL bypass. Inputs containing a trailing newline or non-ASCII digit characters pass the validators but are then re-encoded by the parser to a different address than the input string spelled. find() and bin_find() can match or miss addresses as a result. Example: my $cidr = Net::CIDR::Lite->new(); $cidr->add("::1\n/128"); $cidr->find("::1a"); # incorrectly returns true See also CVE-2026-45191.
CVE-2025-12659 1 Siemens 1 Simcenter Femap 2026-05-12 N/A
The affected applications contains a memory corruption vulnerability while parsing specially crafted IPT files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-27349, ZDI-CAN-27389)
CVE-2026-4892 1 Dnsmasq 1 Dnsmasq 2026-05-12 8.4 High
A heap-based out-of-bounds write vulnerability in the DHCPv6 implementation of dnsmasq allows local attackers to execute arbitrary code with root privileges via a crafted DHCPv6 packet.
CVE-2026-5172 1 Dnsmasq 1 Dnsmasq 2026-05-12 7.5 High
A buffer overflow in dnsmasq’s extract_addresses() function allows an attacker to trigger a heap out-of-bounds read and crash by exploiting a malformed DNS response, enabling extract_name() to advance the pointer past the record’s end.
CVE-2026-4891 1 Dnsmasq 1 Dnsmasq 2026-05-12 5.3 Medium
A heap-based out-of-bounds read vulnerability in the DNSSEC validation of dnsmasq allows remote attackers to cause a denial of service via a crafted DNS packet.
CVE-2026-41509 2 Cross-crypto, Cross-signature 2 Cross-implementation, Cross-implementation 2026-05-12 9.8 Critical
CROSS implementation contains reference and optimized implementations of the CROSS post-quantum signature algorithm. Prior to commit fc6b7e7, there is a buffer overflow in crypto_sign_open() caused by an underflow of the integer mlen. This issue has been patched via commit fc6b7e7.
CVE-2026-34961 1 Barebox 1 Barebox 2026-05-12 6.2 Medium
barebox prior to version 2026.04.0 contains out-of-bounds read vulnerabilities in ext4 extent parsing due to missing validation of the eh_entries field against buffer capacity in fs/ext4/ext4_common.c. Attackers can supply a malicious ext4 filesystem image via USB, SD card, or network boot to trigger heap out-of-bounds reads during boot-time filesystem parsing, potentially redirecting reads to arbitrary disk offsets.
CVE-2026-43916 2026-05-12 N/A
pam_authnft is a PAM session module binding nftables firewall rules to authenticated sessions via cgroupv2 inodes. Prior to 0.2.0-alpha, a heap buffer over-read in peer_lookup_tcp (src/peer_lookup.c:134, prior to the fix) allowed a crafted NETLINK_SOCK_DIAG reply to slip past the message-size check, then dereference past the end of the allocation. This vulnerability is fixed in 0.2.0-alpha.
CVE-2026-42050 1 Imagemagick 1 Imagemagick 2026-05-12 5.5 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-21 and 6.9.13-46, a malicious MIFF file could trigger an overflow when a user opens it in the display tool and right-clicks a tile to invoke the Load / Update menu item. This vulnerability is fixed in 7.1.2-21 and 6.9.13-46.
CVE-2026-34960 1 Barebox 1 Barebox 2026-05-12 6.5 Medium
barebox prior to version 2026.04.0 contains an out-of-bounds read vulnerability in DHCP option parsing within the dhcp_message_type() function that fails to verify the options pointer remains within received packet bounds. An attacker on the same broadcast domain can send a crafted DHCP Offer or ACK packet without a proper 0xff end marker to cause the parser to read past valid packet data and potentially crash the system.
