libxfonts2: libXfont2: Privilege Escalation via Heap Buffer Overflow in Font Server Client

A flaw was found in the libXfont2 font-server client. This heap buffer overflow vulnerability allows a malicious font server to send specially crafted glyph data. The fsreadglyphs function fails to properly validate the total size of the incoming data, leading to an overwrite of memory beyond the...

libxfont2: Font Server Client encoding[] Out-Of-Bounds Read/Write

A flaw was found in the libXfont2 font-server client. A remote attacker, by operating a malicious font server, could exploit an out-of-bounds read/write vulnerability. This occurs because the client incorrectly handles font data, leading to an out-of-bounds memory access. This can lead to privile...

libssh2: libssh2: Information disclosure and potential arbitrary code execution via heap out-of-bounds read

A missing bounds check in the libssh2 publickey subsystem allows malicious SSH servers to trigger a client-side out-of-bounds read, leaking heap pointers that could enable security bypasses, denial of service, or code execution...

USN-8706-1: zlib vulnerability

It was discovered that zlib incorrectly handled negative length parameters in CRC32 combine functions. An attacker could use this issue to cause a denial of service via excessive CPU consumption...

CVE-2026-14366

The Silicon Labs SiWx917 WiFi driver's transmit callback siwx91xsend in drivers/wifi/siwx91x/siwx91xwifi.c frees a network packet it does not own. In the Zephyr TX path the netpkt is owned by the L2/networking stack; the driver only borrows it to copy the frame bytes into a local netbuf. Before t...

CVE-2026-62309

A flaw was found in CoreDNS. A remote attacker can send a specially crafted 28-byte UDP datagram to a CoreDNS server with the proxyproto plugin enabled. This malformed datagram can cause the CoreDNS process to crash, leading to a denial of service DoS. The vulnerability arises from improper...

CVE-2026-27852

A flaw was found in dovecot. A remote attacker can craft a malicious email with an excessive number of email addresses or MIME parameters in its headers. When a user attempts to read this message over IMAP, the parsing process consumes an inordinate amount of memory, leading to the termination of...

CVE-2026-80692

A flaw was found in the Bluetooth hcisync component of the Linux kernel. This vulnerability, a Use-After-Free UAF, could allow a local attacker to potentially cause a system crash or execute unauthorized code. This occurs if a connection object is released from memory while the hcisync task is...

CVE-2026-80651

A flaw was found in the Linux kernel's crypto: ccp/sev-dev-tsm module. The dsmcreate function fails to properly validate the pdev-bus pointer, leading to a null pointer dereference. A local attacker could exploit this vulnerability to trigger a kernel crash, resulting in a Denial of Service DoS...

Updated c-ares packages fix security vulnerabilities

Use-after-free / double-free in c-ares query-completion handling, remotely triggerable via aresgetaddrinfo over TCP. CVE-2026-33630 CPU-exhaustion denial of service via unbounded DNS name compression pointer chains. CVE-2026-69184 Memory-amplification denial of service via unvalidated DNS header...

MGASA-2026-0343 Updated c-ares packages fix security vulnerabilities

Use-after-free / double-free in c-ares query-completion handling, remotely triggerable via aresgetaddrinfo over TCP. CVE-2026-33630 CPU-exhaustion denial of service via unbounded DNS name compression pointer chains. CVE-2026-69184 Memory-amplification denial of service via unvalidated DNS header...

sqlite: SQLite: Arbitrary code execution via crafted FTS5 full-text search data

A flaw was found in SQLite's FTS5 full-text search extension. This vulnerability involves memory corruption, specifically an out-of-bounds read and a heap buffer overflow, which can be triggered by supplying a crafted database with malformed FTS5 page data. When an FTS5 MATCH query is executed...

gzip: gzip: Information disclosure via global buffer overflow in LZH decompression

A flaw was found in GNU gzip. This global buffer overflow vulnerability in the LZH decompression logic is caused by improper reuse of shared global state between different decompression formats. An attacker can exploit this by providing a specially crafted LZW file followed by a specially crafted...

kernel: dm log: fix out-of-bounds write due to region_count overflow

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

kernel: netfilter: ctnetlink: ensure safe access to master conntrack

A flaw was found in the netfilter: ctnetlink component of the Linux kernel. This vulnerability occurs due to insufficient locking when accessing the master conntrack object, allowing it to become invalid while still being referenced. A local attacker could potentially exploit this race condition,...

CVE-2026-26446

A flaw was found in Stomper. An unauthenticated client can trigger a denial of service by closing their TCP connection at specific points while a broker is sending data. This action causes the server process to receive a SIGPIPE signal, leading to its immediate termination and a denial of service...

CVE-2026-80701

A flaw was found in the Linux kernel's drm/vmwgfx component. A local attacker with DRM master privileges could exploit this by providing oversized cursor dimensions through the DRMIOCTLMODECURSOR2 interface. This improper input validation can lead to a kernel crash, resulting in a Denial of Servi...
