kernel: libceph: fix potential use-after-free in have_mon_and_osd_map()

A use-after-free vulnerability was found in the Ceph client session initialization in the Linux kernel. The havemonandosdmap function checks map epochs without holding the appropriate locks, racing with concurrent map updates that free the old map. This can result in dereferencing freed memory...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the gfs2 fiemap function where iomap fiemap is called while the inode glock global lock is held. This can result in recursive glock acquisition if the fiemap buffer is...

The vulnerability of the ext4_bmap() function in the fs/ext4/inode.c file of the Ext4 file system in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the ext4bmap function in the fs/ext4/inode.c file of the Ext4 file system in the Linux operating system is related to the copying of buffers without checking the size of the input data a classic buffer overflow attack. Exploiting this vulnerability could allow an attacker to...

Name of the Vulnerable Software and Affected Versions FUXA versions prior to 1.2.10 Description FUXA, a web-based Process Visualization SCADA/HMI/Dashboard software, contains a path traversal issue that allows an unauthenticated remote attacker to write arbitrary files to any location on the serv...

Insufficient Verification of Data Authenticity

Overview Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity due to the measured boot not validating the integrity of the entire root filesystem. An attacker can gain unauthorized access to sensitive data or modify system files by physically replacin...

EVE Doesn't Protect Rootfs

Impact Measured boot validates BIOS, grub, kernel cmdline, and initrd but not the entire rootfs. Thus, an attacker can create an EVE-OS rootfs squashfs image with some files modified and take out the disk and replace the existing rootfs image without that being detected by measure boot and remote...

GHSA-5H7V-G49C-H887 EVE Doesn't Protect Rootfs

Impact Measured boot validates BIOS, grub, kernel cmdline, and initrd but not the entire rootfs. Thus, an attacker can create an EVE-OS rootfs squashfs image with some files modified and take out the disk and replace the existing rootfs image without that being detected by measure boot and remote...

CVE-2026-25539

SiYuan is a personal knowledge management system. Prior to version 3.5.5, the /api/file/copyFile endpoint does not validate the dest parameter, allowing authenticated users to write files to arbitrary locations on the filesystem. This can lead to Remote Code Execution RCE by writing to sensitive...

CVE-2026-25121 apko is vulnerable to path traversal in apko dirFS which allows filesystem writes outside base

apko allows users to build and publish OCI container images built from apk packages. From version 0.14.8 to before 1.1.1, a path traversal vulnerability was discovered in apko's dirFS filesystem abstraction. An attacker who can supply a malicious APK package e.g., via a compromised or typosquatte...
