CVE-2026-53395

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd. A remote attacker can exploit this vulnerability by sending specially crafted NFS CREATE requests that include conflicting Access Control List ACL attributes. This leads to a memory leak, where the system fails to release...

USN-8566-1 linux, linux-gcp, linux-gke, linux-realtime vulnerabilities

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...

CVE-2026-63797

A flaw was found in the Linux kernel's rpmsg character device. This vulnerability, a use-after-free, occurs during the probe process when an internal pointer to a device endpoint eptdev is prematurely stored. If an error occurs during the device's addition, the eptdev memory is freed, but the...

CVE-2026-64113

A flaw was found in the Linux kernel's ixgbevf network driver. This vulnerability, a use-after-free, occurs when the driver attempts to process network packets for a specific multicast workaround. An attacker could potentially exploit this by sending specially crafted network traffic, which may...

CVE-2026-63795

A flaw was found in the Linux kernel's 9p filesystem client. A reference counting error in the p9clientwalk function can lead to a use-after-free or reference count underflow. This vulnerability may allow a local attacker to cause a system crash, resulting in a Denial of Service, or potentially...

CVE-2026-63794

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM module, specifically within the Secure Virtual Machine SVM component. The sevdbgcrypt function, when handling encryption, incorrectly calculates the transfer length, leading to a page overflow. This memory corruption can resu...

CVE-2026-53399

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When a setlease operation fails, the system prematurely releases a layout state identifier. An attacker could exploit this by triggering the failure, leading to a use-after-free vulnerability. This could result in a system...

CVE-2026-53393

A flaw was found in the Linux kernel's Network File System NFS daemon. This vulnerability occurs when the NFS daemon fails to reset the write verifier during deferred writeback errors for UNSTABLE writes. A remote attacker, acting as an NFS client, could exploit this by performing operations that...

CVE-2026-53398

A flaw was found in the Linux kernel's Network File System Daemon NFSD. The nfsd4decodesecinfononame function does not properly initialize a pointer sinexp before processing an incoming data stream. If the data stream is malformed or truncated, the uninitialized pointer can retain stale data from...

CVE-2026-53396

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd within the nfsd4createfile function. This vulnerability allows a remote attacker to cause a denial of service DoS by repeatedly triggering a memory leak of posixacl allocations. The leak occurs when a client attempts to...

CVE-2026-53392

A flaw was found in the Linux kernel's NFSv4 Network File System version 4 flexfiles component. This vulnerability occurs when the fflayoutalloclseg function processes a malformed flexfiles layout that specifies a zero filehandle version count. An attacker could exploit this by providing a...

CVE-2026-53391

A flaw was found in the Linux kernel's NFSv4/pNFS implementation. The nfs4decodempdsaddr function, responsible for decoding network address information, does not properly handle zero-length raddr opaque data. A malicious or compromised metadata server can exploit this by providing a zero-length...

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-2026-53387

A flaw was found in the Linux kernel's veml6075 light sensor driver. The driver performs an out-of-bounds array access when processing certain index values from the VEML6075CONFIT register. This issue could potentially lead to system instability or a denial of service if triggered by a faulty...

CVE-2026-64181

A flaw was found in the Linux kernel's memory management subsystem. On 32-bit x86 systems with Transparent Huge Pages THP enabled, a missing feature for handling special page table entries can lead to incorrect tracking of memory resources. This can result in system warnings, errors related to...

CVE-2026-53388

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. The fusetrymovefolio function, responsible for managing page cache folios, fails to re-lock a request after initially unlocking it on a successful path. This oversight allows another function, fusechanabort, to...

CVE-2026-64068

A flaw was found in the Linux kernel's netfs component. This vulnerability arises from missing locking around the retry logic when adding new subrequests within the netfsretryreadsubrequests and netfsretrywritestream functions. An attacker could potentially exploit this race condition, which may...

CVE-2026-64052

A flaw was found in the Linux kernel's bio-integrity module. The biointegritymapuser function does not correctly handle partially pinned user pages, which can occur when pinuserpagesfast returns fewer pages than requested. This oversight leads to a null-pointer dereference when attempting to acce...

CVE-2026-53384

A flaw was found in the Linux kernel's 8250dw serial driver. When the clknotifierregister function fails during the probe process, the 8250 port is not properly unregistered. This oversight can lead to a use-after-free vulnerability, where previously freed memory is still referenced. An attacker...

CVE-2026-64150

A flaw was found in the Netfilter component of the Linux kernel. In the nftinner module, an error path incorrectly re-enables softirqs before releasing a local lock. This improper ordering of lock operations could lead to a race condition, potentially allowing a local attacker to cause a denial o...
