Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick, specifically in the code file coders/bmp.c. An attacker who submits a crafted file processed by ImageMagick could trigger undefined behavior, resulting in values that are outside the range of the type unsigned int. This likely leads to a disruption in the...

Astra Linux – Vulnerability in imagemagick

An integer overflow issue was discovered in ImageMagick’s ExportIndexQuantum function in MagickCore/quantum-export.c. Function calls to GetPixelIndex could result in values that are outside the representable range for ‘unsigned char’. When ImageMagick processes a specially crafted PDF file, this...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: libceph: Use u32 for non-negative values in cephmonmapDecode This patch fixes unnecessary implicit conversions that change the signedness of bloblen and nummon in cephmonmapDecode. Currently, bloblen and nummon are signed int...

Astra Linux – Vulnerability in imagemagick

A vulnerability was discovered in ImageMagick, causing a value of type ‘unsigned char’ to fall outside the representable value range when crafted or untrusted input is processed in the coders/psd.c file. This results in a negative impact on the availability of the application or other problems...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06, where it incorrectly enabled the use of the ACPI command when Secure Boot was enabled. This flaw allows an attacker with privileged access to create a Secondary System Description Table SSDT containing code that can overwrite the Linux...

Astra Linux – Vulnerability in exiv2

Exiv2 0.27.2 allows attackers to cause a crash in the Exiv2::getULong function in types.cpp, when called from Exiv2::Internal::CiffDirectory::readDirectory in crwimageint.cpp. This occurs because there is no validation of the relationship between the total size and the offset and size...

Netlink has this pattern in some places: c if atomicread&sk-skrmemalloc sk-skrcvbuf atomicaddskb-truesize, &sk-skrmemalloc; This issue was also fixed in commit 5a465a0da13e “udp: Fixe...

CVE-2026-97876

A local attacker with control over GRUB's configuration can bypass lockdown restrictions when booting with Secure Boot and load an unsigned GRUB module, while GRUB continues to report lockdown is enabled. The vulnerability is caused by insufficient validation of the MMIO base address passed to th...

MikroTik RouterOS Missing Authentication for Critical Function (CVE-2026-67277)

RouterOS accepts a related btest connection before the corresponding primary session has completed authentication. An unauthenticated client can use this state to start an IPv4 UDP test. With random- data=false, the sender transmits an uninitialized tail from a kernel packet buffer. A separate...
