CVE-2026-46406 Claude Code: Insecure Temporary File in /copy Command Enables Response Disclosure and Symlink-Based File Write

Claude Code is an agentic coding tool. From 2.1.59 until 2.1.128, the Claude Code /copy command wrote responses to a hardcoded, predictable path /tmp/claude/response.md without UID isolation, randomness, or symlink protection. The file was created world-readable 0644 in a world-traversable...

CVE-2026-54371 attr < 2.6.0 Symlink Traversal Privilege Escalation via getfattr/setfattr

attr before version 2.6.0 contains a symlink traversal vulnerability in the getfattr and setfattr utilities that allows local attackers to escalate privileges by replacing a pathname component with a symbolic link during directory hierarchy traversal. Attackers who control a pathname component ca...

CVE-2026-54369 acl < 2.4.0 Symlink Traversal Privilege Escalation via libacl Functions

acl before version 2.4.0 contains a symlink traversal vulnerability in the libacl pathname-based functions aclgetfile, aclsetfile, aclextendedfile, and acldeletedeffile that allows local attackers to escalate privileges by replacing any pathname component with a symbolic link. Attackers who contr...

CVE-2026-53306

A flaw was found in the Linux kernel. An off-by-one error in the hvciucv module can allow a local attacker to cause an out-of-bounds write. This memory corruption could lead to a denial of service DoS or potentially other impacts...

CVE-2026-53296

A flaw was found in the Linux kernel, specifically within the mailbox-test component. This vulnerability occurs when channels are not correctly released during a probe error, leading to a memory leak and a Use-After-Free UAF condition. A Use-After-Free UAF is a memory corruption vulnerability tha...

kernel: drm/amd/display: Do not skip unrelated mode changes in DSC validation

A flaw was found in the Linux kernel's AMD display component. This vulnerability arises from incorrect validation of display mode changes during Display Stream Compression DSC processing. A local attacker could exploit this by initiating specific display configuration changes, which may lead to a...

kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...

CVE-2026-57919

PBackupVSS.exe in Matrix42 Empirum before 25.5 and 26.x before 26.2 creates a named pipe \.\pipe\PBackupVSS with a DACL that grants GENERICREAD and GENERICWRITE permissions to all authenticated users. A low-privileged local attacker can connect to this pipe and send crafted IPC messages to trigge...

JLSEC-2026-637

Buffer Overflow vulnerability in Ffmpeg v.N113007-g8d24a28d06 allows a local attacker to execute arbitrary code via the libavfilter/avfshowspectrum.c:1789:52 component in showspectrumpicrequestframe...

CVE-2026-57454

A flaw was found in Vim, an open source command-line text editor. A local attacker could exploit this vulnerability by providing a specially crafted undo or swap file. When Vim processes this file, an out-of-bounds read occurs, which can lead to the disclosure of sensitive information from memory...

CVE-2026-53063

A flaw was found in the Linux kernel's device-mapper dm cache component. Incomplete logic within the invalidateremove function, which handles write operations after cache invalidation, can lead to a system hang. This occurs because the function sets up remapping for write operations but fails to...

CVE-2026-52952

A flaw was found in the Linux kernel's Input/Output Memory Management Unit IOMMU subsystem, which manages how devices access system memory. A race condition, a situation where multiple operations occur in an unpredictable order, exists during device recovery when multiple memory domains are being...

bzip2: bzip2: Denial of Service in bzip2recover via a specially crafted file

A flaw was found in bzip2. The bzip2recover utility contains an off-by-one error that allows a local attacker to cause an out-of-bounds write to a global buffer by processing a specially crafted file. This memory corruption can lead to a crash, resulting in a Denial of Service DoS...

CVE-2026-52970

A flaw was found in the netfilter: nftct component of the Linux kernel. The nftctexpectobjeval function allocates an expectation but fails to release its local reference. This oversight leads to a resource leak, which could potentially allow a local attacker to cause a denial of service by...

CVE-2026-52992

A flaw was found in the Linux kernel's Advanced Disc Filing System ADFS component. This vulnerability allows a local attacker to cause an out-of-bounds write by providing a specially crafted ADFS disc record with a zero zone count. This can lead to memory corruption, potentially resulting in a...

CVE-2026-53060

A flaw was found in the Linux kernel's device-mapper dm cache metadata. This memory leak vulnerability occurs when the dmcachemetadataabort function fails to acquire the root lock because the block manager is read-only, leading to the improper release of a temporary block manager. A local attacke...

CVE-2026-53154

A flaw was found in the Linux kernel's huge page hugetlb memory management. When an error occurs during the copying of huge pages, the system fails to properly restore the memory reservation. This can lead to a leak of the virtual memory area VMA reservation. A local attacker could exploit this b...

CVE-2026-53188

A flaw was found in the Linux kernel's RDMA/core component. This vulnerability arises from insufficient validation of file operations fops passed to the ibgetucaps function. A local attacker could exploit this by creating a block device with a device number devt that aliases a character device...

CVE-2026-53210

A flaw was found in the Linux kernel's Trusted Execution Environment TEE subsystem. A shared memory shm leak occurs in the registershmhelper function when TEEIOCSHMREGISTER is called with a zero-length shared memory registration. This can be triggered by a local attacker, potentially leading to a...
