Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal in the staging/src/k8s.io/kubectl/pkg/cmd/cp/filespec.go path handling logic. An attacker who controls the tar output from a container can write files to arbitrary locations on a Windows user’s local machine by causi...

gstreamer-plugins-good: GStreamer: Remote code execution via MRF file parsing

A flaw was found in GStreamer. This out-of-bounds write vulnerability occurs during the parsing of MRF files due to improper validation of user-supplied data. A remote attacker could exploit this by tricking a user into visiting a malicious page or opening a malicious file. Successful exploitatio...

CVE-2026-19444

A flaw was found in Kubernetes kubectl. An attacker controlling a container can write arbitrary files to the host system when a user copies files from the container. Because the tool does not properly validate file paths when extracting archives on Windows, a malicious container can traverse...

Important: Red Hat Security Advisory: kernel security update

An update for kernel is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from th...

kernel: Linux kernel: libceph stack out-of-bounds write via crafted OSDMap

A flaw was found in libceph in the Linux kernel. A remote attacker, acting as a malicious monitor, could send a specially crafted OSDMap Object Storage Device Map with an overly long pgtemp or pgupmap entry. This could lead to a stack out-of-bounds write, resulting in a kernel bug and potentially...

CVE-2026-98120

A flaw was found in the Linux kernel's netfs network filesystem subsystem. A local user can cause a Denial of Service DoS by initiating specific unbuffered write operations on an affected filesystem. When a write subrequest encounters zero-length data during preparation, the kernel fails to relea...
