This new Linux kernel bug called Copy Fail (CVE-2026-31431) is kinda terrifying because it’s not complicated at all. A normal user can run a tiny 732-byte script and get root, no race conditions or luck required, and it works across major distros like Ubuntu, RHEL, and SUSE. The exploit quietly modifies the page cache instead of the file on disk, so integrity checks don’t catch it, but the kernel still executes the tampered version in memory.
Even worse, since the page cache is shared, it can potentially cross container boundaries too. Patch ASAP if your distro hasn’t already, because this one feels way too reliable…
Integer overflows were discovered in the functions grubcmdinitrd and grubinitrdinit in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions.
"grub2 contains a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing."
GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions.

A Inclusion of Sensitive Information in Log Files vulnerability in yast2-rmt of SUSE Linux Enterprise Server 15; openSUSE Leap allows local attackers to learn the password if they can access the log file. This issue affects: SUSE Linux Enterprise Server 15 yast2-rmt versions prior to 1.2.2. openSUSE Leap yast2-rmt versions prior to 1.2.2.
In phpMyAdmin 4 before 4.9.4 and 5 before 5.0.1, SQL injection exists in the user accounts page. A malicious user could inject custom SQL in place of their own username when creating queries to this page. An attacker must have a valid MySQL account to access the server.
The /usr/sbin/pinger binary packaged with squid in SUSE Linux Enterprise Server 15 before and including version 4.8-5.8.1 and in SUSE Linux Enterprise Server 12 before and including 3.5.21-26.17.1 had squid:root, 0750 permissions. This allowed an attacker that compromissed the squid user to gain persistence by changing the binary
A flaw was found in Node.js before 6.15.0 and 8.14.0. An HTTP request splitting. If Node.js can be convinced to use unsanitized user-provided Unicode data for the path option of an HTTP request, then data can be provided which will trigger a second, unexpected, and user-defined HTTP request to made to the same server.

A flaw was found in Node.js versions before 6.15.0, 8.14.0, 10.14.0 and 11.3.0. A Slowloris HTTP Denial of Service. An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time.

In libwpd 0.10.2, there is a NULL pointer dereference in the function WP6ContentListener::defineTable in WP6ContentListener.cpp that will lead to a denial of service attack. This is related to WPXTable.h.
An issue was discovered in modaliasphysicalhandler in modalias.c in lighttpd before 1.4.50. There is potential ../ path traversal of a single directory above an alias target, with a specific modalias configuration where the matched alias lacks a trailing '/' character, but the alias target filesystem path does have a trailing '/' character.

A flaw was found in ansible. ansible.cfg is read from the current working directory which can be altered to make it point to a plugin or a module path under the control of an attacker, thus allowing the attacker to execute arbitrary code.
A vulnerability in pammodules of SUSE Linux Enterprise allows attackers to log into accounts that should have been disabled. Affected releases are SUSE Linux Enterprise: versions prior to 12.
An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited.
Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks.
The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename.
coders/tiff.c in ImageMagick allows remote attackers to cause a denial of service (application crash) via vectors related to the "identification of image."
A vulnerability was found in ImageMagick. Insufficient filtering for filename passed to delegate's command allows remote code execution during conversion of several file formats.
ImageMagick allows to process files with external libraries. This feature is called 'delegate'. It is implemented as a system() with command string ('command') from the config file delegates.xml with actual value for different params (input/output filenames etc). Due to insufficient %M param filtering it is possible to conduct shell command injection. One of the default delegate's command is used to handle https requests:
"wget" -q -O "%o" "https:%M"
where %M is the actual link from the input. It is possible to pass the value like https://example.com"|ls "-la and execute unexpected 'ls -la'. (wget or curl should be installed).
A stack overflow vulnerability was found in nan functions that could cause applications which process long strings with the nan function to crash or, potentially, execute arbitrary code.

The DispatchWrite function in proxy/dispatcher/idirectfbsurfacedispatcher.c in DirectFB 1.4.4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers an out-of-bounds write.
Multiple integer signedness errors in the DispatchWrite function in proxy/dispatcher/idirectfbsurfacedispatcher.c in DirectFB 1.4.13 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers a stack-based buffer overflow.
