CVE-2026-63892

A flaw was found in the Linux kernel's Thunderbolt property driver. When processing Thunderbolt properties on a non-root path, a crafted entry with a small entry-length value can lead to an out-of-bounds read. This occurs because the kmemdup function reads beyond the intended memory block and a...

CVE-2026-63890

A flaw was found in the Linux kernel's Fibre Channel over Ethernet FCoE module. An unauthenticated attacker on the same Layer 2 L2 network segment could send a specially crafted FCoE Initialization Protocol FIP frame with a malformed descriptor. This could lead to an infinite loop, causing a deni...

CVE-2026-65061

Data::ReqRep::Shared versions before 0.05 for Perl create a world-readable mmap backing file and open it without OEXCL or ONOFOLLOW. The segment is created in reqrep.h with openpath, ORDWR | OCREAT, 0666, for both the request-reply and the integer-variant segments. The mode is 0666, so under the...

CVE-2026-64616

Data::NDArray::Shared versions before 0.02 for Perl create a world-readable mmap backing file and open it without OEXCL or ONOFOLLOW. The segment is created in ndarray.h with openpath, ORDWR|OCREAT, 0666. The mode is 0666, so under the default umask 022 the file is created mode 0644 world-readabl...

CVE-2026-47671

Nhost is an open source Firebase alternative with GraphQL. In versions of Nhost CLI prior to 1.46.0, the hidden nhost configserver used by nhost dev exposes the Mimir GraphQL API with dummy authorization directives and permissive CORS. When a developer is running the local development environment...

CVE-2026-47671 Nhost CLI local configserver allows cross-origin unauthenticated read/write access to local development configuration and secrets

Nhost is an open source Firebase alternative with GraphQL. In versions of Nhost CLI prior to 1.46.0, the hidden nhost configserver used by nhost dev exposes the Mimir GraphQL API with dummy authorization directives and permissive CORS. When a developer is running the local development environment...

CVE-2026-47671

Nhost CLI prior to 1.46.0 exposes an unauthenticated, cross-origin-configurable configserver via nhost dev. The hidden configserver serves Mimir GraphQL with dummy authorization and permissive CORS (Access-Control-Allow-Origin: *). An attacker-controlled web page can reach localhost and perform q...

CVE-2026-63880

A flaw was found in the Linux kernel's drm/amdgpu graphics driver. An unprivileged local attacker with access to /dev/dri/renderD can trigger an out-of-memory condition during a specific graphics operation, leading to a resource lock not being released. This lock leak causes subsequent operations...

GHSA-V396-V7Q4-X2QJ GitPython unsafe clone option gate bypass through joined short options

GitPython version 3.1.50 blocks unsafe git clone options such as --upload-pack, -u, --config, and -c unless callers explicitly pass allowunsafeoptions=True. However, the default unsafe-option gate does not recognize joined short-option forms such as -u/path/to/helper. Git itself accepts -u as the...

CVE-2026-65068

CVE-2026-65068 affects Data::SpatialHash::Shared prior to 0.02 for Perl. The code opens a shared mmap backing file with open(path, O_RDWR|O_CREAT, 0666) and creates the file with mode 0666 (often 0644 under default umask) in a world‑readable location (e.g., /tmp or /dev/shm). Because O_NOFOLLOW i...

CVE-2026-63860

A flaw was found in the Linux kernel's RDMA/core component. This vulnerability arises from the improper handling of Netlink Attribute NLA strings, where attributes evaluated as C-strings do not properly check for a null terminator. A local attacker could potentially provide specially crafted inpu...

kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

CVE-2026-63952

A flaw was found in the Linux kernel's memfd component. When the SEALEXEC flag is used to create a memory file descriptor, the SEALWRITE flag is implicitly applied to prevent writing to executable memory. However, this implicit write protection is applied after checks that should deny writable...

USN-8580-1 accountsservice vulnerabilities

It was discovered that the Ubuntu-specific SetLanguage patch to AccountsService incorrectly handled dropping privileges. A local attacker could use this issue to execute arbitrary commands as an administrator. CVE-2026-61897 It was discovered that the Ubuntu-specific SetLanguage helpers for...

CVE-2026-63988

A flaw was found in the Linux kernel's bridge module. A local user, by interacting with the sysfs path for bridge port attributes, could trigger a 'sleep in atomic context' issue. This occurs because the brportstore function, while holding a lock that requires an atomic context, calls a function...

libssh: libssh: authentication bypass via missing GSSAPI principal check

A flaw was found in libssh. On servers with GSSAPIKeyExchange enabled, the gssapi-keyex path does not verify whether the authenticated Kerberos principal is authorized for the requested local user, allowing authenticated clients to log in as arbitrary users...

CVE-2026-63917

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface vti6 component. An unprivileged local user, particularly within a user namespace, could exploit a vulnerability related to incorrect network namespace handling during the movement of a vti6 tunnel. This issue can lead to a kerne...
