UBUNTU-CVE-2026-61666

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.2, WebSocket::Driver.server passes a malformed Host header to URI.parse in lib/websocket/http/request.rb without catching URI::InvalidURIError, allowing a remote client to crash a TCP-backed WebSocket server when th...

kernel: drm/amd/display: Validate payload length and link_index in dc_process_dmub_aux_transfer_async

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Validate payload length and linkindex in dcprocessdmubauxtransferasync Why&How dcprocessdmubauxtransferasync copies payload-length bytes into a 16-byte stack buffer dpaux.data16 guarded only by an ASSERT, which i...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...

EUVD-2026-60269

The WNC-M14A2A LTE-M modem driver mishandles unsolicited %NOTIFYEV: events in oncmdsocknotifyev drivers/modem/vendorstandalone/wncm14a2a.c. The response line is linearized into a fixed 40-byte stack buffer via netbuflinearize, which caps the copy at 39 bytes and returns outlen = 39. The two...

CVE-2026-12519

CVE-2026-12519 is an out-of-bounds stack read and write in the Zephyr RTOS WNC-M14A2A LTE-M modem driver, specifically in on_cmd_socknotifyev() (drivers/modem/vendor_standalone/wncm14a2a.c). Two quote-delimiter scanning loops were bounded by the full frame length (len) instead of the linearized b...

kernel: dlm: validate length in dlm_search_rsb_tree

A flaw was found in the Linux kernel's Distributed Lock Manager dlm module. An attacker could send specially crafted network messages with an oversized length parameter to the dlmdumprsbname function. This lack of validation can lead to an out-of-bounds write in the dlmsearchrsbtree function,...

CVE-2026-45699

A flaw was found in Netatalk. An integer underflow vulnerability exists in the copydir function of the afpd daemon. This flaw occurs when a file operation crosses a device boundary within an Apple Filing Protocol AFP shared volume. Incorrect calculation of buffer size can lead to a stack-based...

389-ds-base: 389-ds-base: pre-authentication stack buffer overflow in get_ruvelement_from_berval() via unbounded replica ID parsing

A stack buffer overflow flaw was found in 389 Directory Server 389-ds-base. The getruvelementfromberval function in repl5ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP...

CVE-2026-68471

A flaw was found in the Wi-Fi IEEE 802.11 component of the Linux kernel. The ieee80211mlecommonsize function uses the first common-info octet as the length for all known MLE Management Link Establishment types. However, the ieee80211mlesizeok function did not properly validate this length for all...
