Bypass-Sandbox-Evasion

绕过沙箱检测 沙箱通常用于分析恶意软件。它们提供了一个临时的、隔离的且安全的环境，用以观察可疑文件是否表现出任何恶意行为。然而，恶意软件开发者已开发出多种方法来逃避沙箱和分析环境。其中一种方法是执行检查，以确定执行恶意软件的机器是否正在由真实用户操作。其中一种检查是RAM大小。如果RAM大小小得不切实际（例如1GB），则可能表明该机器是一个沙箱。如果恶意软件检测到沙箱，它将不会执行其真正的恶意行为，并可能表现为一个良性文件。 详细说明 GetPhysicallyInstalledSystemMemory API 从 SMBIOS 固件表中检索计算机上实际安装的 RAM 数量。它接受一个...

check_icmp_dos-CVE-2018-4407-

SUSE CVE-2026-93148

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject MEMALLOC BTF accesses past object bounds BTF struct walks relax the struct-size check for accesses through a trailing flexible array. That is valid for ordinary BTF type walking, but PTRTOBTFID | MEMALLOC values point...

OESA-2026-3815 pcre2 security update

PCRE2 is a re-working of the original PCRE1 library to provide an entirely new API. Since its initial release in 2015, there has been further development of the code and it now differs from PCRE1 in more than just the API. PCRE2 is written in C, and it has its own API. There are three sets of...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: nilfs2: A shift-out-of-bounds condition has been fixed due to an overly large exponent of the block size. If the slogblocksize field in the superblock data is corrupted and too large, initnilfs and loadnilfs may still trigger a...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Validating UAC3 cluster segment descriptors UAC3 class segment descriptors need to be verified to ensure that their sizes match the declared lengths, and that they fit within the allocated buffer sizes as well...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the Big Requests extension. The length of the request is multiplied by 4 before checking against the maximum allowed size, which may lead to an integer overflow and bypassing the size check...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: transportipc: Validate the payload size before reading the handle. The handleresponse function dereferences the payload as a 4-byte handle without verifying that the declared payload size is at least 4 bytes. A malformed o...
