USN-8569-1: Linux kernel (HWE) vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

CVE-2026-53402

A flaw was found in the Linux kernel's framebuffer console fbcon component. When the fbcondosetfont function fails, the system's error handling does not correctly restore the font state, leading to a desynchronized terminal. A local user can exploit this by providing character indices that cause ...

USN-8567-1: Linux kernel vulnerabilities

CVE-2026-52349

Directory Traversal vulnerability in Menyoo 2.0 Versions before commit 729aa48: fixed in commit 729aa48 allows a local attacker to execute arbitrary code via the Spooner file management, VehicleSpawner save/folder/rename functionality, WeaponOptions save/folder/rename functionality,...

CVE-2026-64042

A flaw was found in the Linux kernel's vfio/pci subsystem. This vulnerability occurs because the Direct Memory Access Buffer DMABUF export mechanism does not adequately verify if Base Address Register BAR resources are properly reserved before allowing access. A local attacker could exploit this ...

CVE-2026-64084

A flaw was found in the Linux kernel's hardware monitoring hwmon subsystem, specifically within the pmbus/adm1266 driver. This vulnerability involves an out-of-bounds memory access, where the system attempts to read or write data beyond the allocated memory region. A local attacker could exploit...

CVE-2026-53378

A flaw was found in the Linux kernel's Direct Rendering Manager DRM color operation module drm/colorop. This vulnerability arises from improper reference tracking of blob properties during state duplication, destruction, and reset operations. An attacker with local access could potentially exploi...

nodejs: Node.js: Unauthorized file metadata modification

A flaw was found in Node.js. The Permission API allows a local user to modify file metadata on paths that have been explicitly set as read-only. This can lead to unauthorized changes in file properties, impacting the integrity of the file system...

DEBIAN-CVE-2026-12080

A flaw was found in the QEMU Guest Agent qga. A local unprivileged user can exploit a vulnerability in the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can occur either through a deterministic directory-symlink bypass or a Time-of-Check to Time-of-Use TOCTOU...

CVE-2026-12080

A flaw was found in the QEMU Guest Agent qga. A local unprivileged user can exploit a vulnerability in the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can occur either through a deterministic directory-symlink bypass or a Time-of-Check to Time-of-Use TOCTOU...

UBUNTU-CVE-2026-12080

A flaw was found in the QEMU Guest Agent qga. A local unprivileged user can exploit a vulnerability in the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can occur either through a deterministic directory-symlink bypass or a Time-of-Check to Time-of-Use TOCTOU...

CVE-2026-64118

A flaw was found in the Linux kernel's qed driver. This vulnerability involves a double free error in the qedcxttablesalloc function, where memory is deallocated twice if a Connection ID CID bitmap allocation fails. This can lead to memory corruption, potentially allowing a local attacker to caus...

CVE-2026-53371

A flaw was found in the Linux kernel's ionic Remote Direct Memory Access RDMA driver. A local user can exploit this vulnerability due to an unbounded read operation when displaying the nodedesc sysfs file. If the nodedesc field is not null-terminated, the system will read beyond its allocated...

CVE-2026-12080

CVE-2026-12080 affects the QEMU Guest Agent (qga). A local, unprivileged user can exploit the guest-ssh-add-authorized-keys handler by manipulating symbolic links through a deterministic directory-symlink bypass or a TOCTOU file-symlink race, enabling ownership of arbitrary root-owned files/direc...

CVE-2026-64121

A flaw was found in the Linux kernel's Intermediate Functional Block ifb network device. A local user with network configuration privileges can trigger a slab-out-of-bounds read by configuring an asymmetric ifb device and querying its ethtool statistics. This vulnerability can lead to a kernel...

CVE-2026-64159

A flaw was found in the Linux kernel's network file system netfs component. This vulnerability occurs when the local file size is larger than the size reported by the remote server, leading to an incorrect update of the 'zero point' a file position used to optimize reads. An attacker could...

CVE-2026-64041

A flaw was found in the Linux kernel's ASoC fs210x audio codec driver. An incorrect use of the strscpy function in fs210xeffectsceneinfo can lead to a buffer overflow. This occurs when a string is copied without proper size validation, potentially allowing a local attacker to cause a denial of...

CVE-2026-64109

A flaw was found in the Linux kernel's afunix UNIX domain sockets component. A race condition in the unixstreamdatawait function allows a local attacker to trigger a Use-After-Free UAF vulnerability. This occurs because the function peeks at a socket buffer without proper locking, enabling anothe...

CVE-2026-64137

A flaw was found in the Linux kernel's Common Internet File System CIFS client. This vulnerability allows an unprivileged local user to send witness notifications or join a specific multicast group without proper administrative privileges. Exploiting this flaw could lead to information disclosure...

dotnet: .NET: Local tampering via improper link resolution

A flaw was found in .NET. This vulnerability, stemming from improper link resolution before file access, allows an authorized local attacker to perform tampering. This could lead to unauthorized modification of data or system files...
