CVE-2026-72678 Memory Allocation with Excessive Size Value in Elasticsearch Leading to Denial of Service
Elasticsearch does not validate a size value taken from a user-supplied input before that value is used to reserve memory for an internal data structure. An authenticated user holding only read privileges can submit a single small crafted request to a product API endpoint that causes the node to...
Memory Allocation With Excessive Size Value
Apache ActiveMQ is vulnerable to Memory Allocation with Excessive Size Value. The vulnerability is due to improper validation of the encoded size of OpenWire message property maps during unmarshaling, which allows an authenticated attacker to send a crafted message with an excessively large size...
EUVD-2026-57039
In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate minimum PDU size for transform requests The receive path applies the minimum SMB2 PDU size check only when ProtocolId is SMB2PROTONUMBER. A packet carrying SMB2TRANSFORMPROTONUM bypasses the check even when the...
CVE-2026-68272
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate CPGFXSHADOW chunk size in CS pass1 Add a minimum-length check for the AMDGPUCHUNKIDCPGFXSHADOW chunk in amdgpucspass1, matching the gate already present for the IB, FENCE and BOHANDLES chunk types. The...

CVE-2026-68258 drm/amdkfd: Check bounds on CRIU restore queue type and mqd size
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check bounds on CRIU restore queue type and mqd size We weren't checking whether the values provided in the private data in kfd CRIU restore were within bounds. For queue type, add a KFDQUEUETYPEMAX and ensure the...
CVE-2026-68097
Summary: CVE-2026-68097 affects the Linux kernel ksmbd path handling POSIX ACLs. The root cause is a check failure in ACE validation: set_ntacl_dacl() validates sid.num_subauth but does not ensure the declared ACE size can contain all sub-authorities, allowing an undersized ACE to be copied and l...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Validating the command header size against SVGACMDMAXDATASIZE This data originates from user space and is used in buffer offset calculations, which may potentially lead to an out-of-bounds access due to overflow...
Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: ALSA: wavefront: Fixed integer overflow in sample size validation The wavefrontsendsample function has a problem with integer overflow when validating sample size. The header-size field is of type u32, but it is cast to int for...
libXfont2: PCF Font Parsing Heap Buffer Overflow
A flaw was found in libXfont2. A specially crafted PCF Portable Compiled Format font file, when processed by libXfont2, can lead to a buffer overflow. This occurs because the font parsing process does not properly validate the size of a bitmap buffer against the glyph metrics provided in the...
CVE-2026-64578 ksmbd: validate compound request size before reading StructureSize2
In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate compound request size before reading StructureSize2 When ksmbd validates a compound chained SMB2 request, ksmbdsmb2checkmessage reads pdu-StructureSize2 without first checking that the compound element is large...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: out-of-bounds read/write in GLX ChangeDrawableAttributes
An out-of-bounds read flaw was found in the X.Org X server and Xwayland in glXDispChangeDrawableAttributes. A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapp...
CVE-2026-67305 FreeRDP Windows Client before 3.29.0 Heap Buffer Overflow via Cliprdr
FreeRDP Windows client before 3.29.0 contains a heap buffer overflow vulnerability in the clipboard virtual channel when processing CLIPRDRFILECONTENTSRESPONSE PDUs without validating the server-provided size against the destination buffer. A malicious RDP server can send a response with a data...
CVE-2026-64527
A flaw was found in the drm/hyperv component of the Linux kernel. The hypervreceivesub function, responsible for processing VMBus packets, does not adequately validate the size of incoming data. This oversight allows a malicious or compromised host to send specially crafted packets, potentially...
CVE-2026-59878 Apache ActiveMQ AMQP, Apache ActiveMQ, Apache ActiveMQ All: AMQP NIO negative frame size validation bypass leading to DoS
