AMSI-ETW-Patch

AMSI-ETW-Patch 该仓库包含如何采用单字节补丁同时修补 AMSI 和 ETW 的信息。 其思路是，由于补丁本身只有一个字节，因此可以限制对该补丁的检测。 AMSI patch-amsi-x64.c 其思路是，AMSI 在到达关键的 AMSI“检查”代码之前会执行大量验证检查。你可以简单地将某个 jz 切换为 jnz，反之亦然。 上图中红色箭头指示关键代码所在的位置。 可切换以避免调用关键代码的检查示例。 在本例中，我们修补 cmp dword ptr rbx, 49534d41h 之后的 jnz。 该补丁只是：AmsiScanBuffer + 0x83 = 0x74 x64。...

Linux Distros Unpatched Vulnerability : CVE-2026-90176

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ksmbd: Do not skip lock checks for single-byte ranges checklockrange uses inclusive ranges. Its callers pass the end offset as start + length - 1, so start == e...

CVE-2026-90176: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Do not skip lock checks for single-byte ranges checklockrange uses inclusive ranges. Its callers pass the end offset as start + length - 1, so start == end represents a valid single-byte range rather than an empty range. T...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-47 and 7.1.2-22, when writing an IPTC output file, a malicious input file could cause an out-of-bounds read of a single byte. This issue has been fixed in versions 6.9.13-47 and...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, an incorrect check in the JP2 library resulted in a heap buffer overwrite of a single byte when certain options were specified. This issue has been fixed in...

Astra Linux – Vulnerability in dnsmasq

A single-byte, non-arbitrary write/use-after-free flaw was discovered in dnsmasq. This flaw allows an attacker to send a crafted packet processed by dnsmasq, potentially causing a denial of service...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: spi: sun6i – reduced the DMA RX transfer width to a single byte. Through empirical testing, it has been determined that sometimes RX SPI transfers with DMA enabled may return corrupted data. This issue arises due to the loss of o...

The vulnerabilities of the functions queue_gso_packets() and queue_userspace_packet() in the openvswitch kernel module of Linux allow a hacker to cause a service failure.

The vulnerability of the queuegsopackets and queueuserspacepacket functions in the openvswitch kernel module of Linux operating systems is related to a single-byte offset error. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...

EUVD-2026-51157

CSL 1010 M2M 3G WiFi Module firmware through 2.2.1.4 contains a weak encryption vulnerability that allows unauthenticated attackers to recover all stored secrets in plaintext by reversing a single-byte XOR cipher with a static key applied to the configuration backup file. Attackers can trivially...

CVE-2026-67596

CSL 1010 M2M 3G WiFi Module firmware through 2.2.1.4 contains a weak encryption vulnerability that allows unauthenticated attackers to recover all stored secrets in plaintext by reversing a single-byte XOR cipher that uses a static key to obfuscate the configuration backup file. Attackers can...

Mozilla Thunderbird < 140.13

The version of Thunderbird installed on the remote Windows host is prior to 140.13. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2026-72 advisory. - Memory safety bugs present in Thunderbird ESR 140.12 and Thunderbird 152. Some of these bugs showed evidence of...

glibc: glibc: Information disclosure or denial of service via ungetwc function with specific wide character encodings

A flaw was found in glibc GNU C Library. When the ungetwc function is called on a file stream using wide characters with specific overlapping single-byte and multi-byte encodings, it may attempt to read data outside of its allocated buffer. This can lead to the unintentional disclosure of sensiti...
