Spectre 攻击例程 2018年1月2日 CVE-2017-5753 和 CVE-2017-5715 "幽灵" Spectre 漏洞利用例子 这是什么？ 我们把文本 "The Magic Words are Squeamish Ossifrage." 放在内存中, 然后我们试图利用漏洞读取他。如果系统易受到攻击, 那么你将在标准输出中看到相同的文本。 在本代码中, 如果 victimfunction 中的编译指令以严格的程序顺序执行, 则该函数只从 array1 0.. 15 中读取, 因为 array1 size = 16。但是, 执行时间超出读取时间是可能的。读取内存 byte...

DEBIAN-CVE-2026-96674

alsa-lib through 1.2.16.1 computes combined topology element size using 32-bit arithmetic in src/topology/ctl.c, allowing integer overflow that defeats bounds checks. Attackers can supply crafted topology files that wrap size calculations, causing the decoder to read beyond the topology buffer an...

gstreamer: gstreamer1-plugins-ugly-free: gstreamer: integer overflow/underflow in asfdemux bounds checks leading to out-of-bounds read

Multiple integer overflow and underflow vulnerabilities were found in the GStreamer gst-plugins-ugly ASF demuxer asfdemux when parsing header objects from crafted ASF, WMV, or WMA files. Insufficient validation of attacker-controlled length and size values can bypass bounds checks and cause...

CVE-2026-89525

A flaw was found in the Linux kernel. A local attacker could craft a malicious Universal Disk Format UDF image to trigger an out-of-bounds read vulnerability in the udfgetpblockvirt15 function. This occurs when the system attempts to read a Virtual Allocation Table VAT index equal to the entry...

UBUNTU-CVE-2026-89634

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix ALIGN overflow in symlinkdata error context loop The check added by commit 7d9a7f1f96cd "smb/client: fix possible infinite loop and oob read in symlinkdata" compared the post-ALIGN length against the remaining...

PT-2026-89741

A flaw was found in GStreamer's gst-plugins-good isomp4 plugin. When processing a specially crafted MP4 or MOV file containing CEA-608 closed-caption data, an integer overflow in 32-bit unsigned arithmetic can bypass a bounds check in the caption parser. This leads to an out-of-bounds heap read o...

CVE-2026-86314

Integer overflow in the source-bounds check in Memory::init src/runtime/Memory.cpp in Samsung walrus on all platforms allows a remote attacker to cause an out-of-bounds heap read and denial of service via a crafted WebAssembly module in which a 32-bit unsigned addition wraps around and bypasses t...

PT-2026-86620

Name of the Vulnerable Software and Affected Versions Samsung walrus version ff3bf5ff5c4878f8e5572c9593d303f6bc997443 Description An integer overflow occurs during the source-bounds check within the Memory::init function located in src/runtime/Memory.cpp. A remote attacker can exploit this by...

kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()

A flaw was found in the Linux kernel's nfnetlinkcthelper component. This vulnerability, an out-of-bounds read, occurs in the nfnlcthelperdumptable function when a network connection tracking helper is removed during a dump operation, leading to a bypassed bounds check. A local attacker could...

SUSE CVE-2026-72225

In the Linux kernel, the following vulnerability has been resolved: jbd2: fix integer underflow in jbd2journalinitializefastcommit jbd2journalinitializefastcommit validates journal capacity by checking journal-jlast - numfcblks JBD2MINJOURNALBLOCKS. Both jlast and numfcblks are unsigned, so when...

SUSE CVE-2026-74394

In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: fix integer overflow in immediate data length check immbuf-len is a user-controlled uint32t received from the network. Adding it to immdataoffset without overflow checking allows a malicious initiator to send...

EUVD-2026-67548

In the Linux kernel, the following vulnerability has been resolved: ntfs: fix u16 truncation of restart-area length check ntfscheckrestartarea validates that the $LogFile restart area and its trailing log client record array fit within the system page size: u16 raofs, ralen, caofs; ... ralen =...

Unity Linux 20.1050a Security Update: kernel (UTSA-2026-104557)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-104557 advisory. In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: fix integer overflow in immediate data length check immbuf-len is a user-controlled...

SUSE CVE-2026-55648

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, freerdpimagecopyfromicondata in libfreerdp/codec/color.c calculates nWidth multiplied by nHeight multiplied by FreeRDPGetBytesPerPixelformat in 32-bit arithmetic. A malicious RDP server can send a RAIL TSICONINFO...

CVE-2026-74306

A flaw was found in the Linux kernel's vfio/qat driver. This vulnerability involves a race condition in the qatvfresumewrite function, where concurrent operations can bypass a critical bounds check. This allows data to be written beyond the intended memory area, potentially corrupting system...

CVE-2026-55648

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, freerdpimagecopyfromicondata in libfreerdp/codec/color.c calculates nWidth multiplied by nHeight multiplied by FreeRDPGetBytesPerPixelformat in 32-bit arithmetic. A malicious RDP server can send a RAIL TSICONINFO...

CVE-2026-55648

The FreeRDP RDP client contains an integer overflow vulnerability in the freerdp_image_copy_from_icon_data function within libfreerdp/codec/color.c. The flaw occurs because the software performs 32-bit arithmetic when calculating the required size based on dimensions provided by a remote RDP serv...

CVE-2026-55648 FreeRDP: Integer Overflow in `freerdp_image_copy_from_icon_data` Bypasses Bounds Check

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, freerdpimagecopyfromicondata in libfreerdp/codec/color.c calculates nWidth multiplied by nHeight multiplied by FreeRDPGetBytesPerPixelformat in 32-bit arithmetic. A malicious RDP server can send a RAIL TSICONINFO...
