CVE Vulnerability Catalog

An improper access control vulnerability in AMD Secure Encrypted Virtualization (SEV) firmware allows a malicious hypervisor to bypass RMP protections, potentially compromising SEV-SNP guest memory integrity.

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok() on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directories.

A vulnerability in the tail utility of uutils coreutils allows exfiltration of sensitive file contents when using the --follow=name option. Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting its contents.

A segmentation fault was discovered in the libde265 library (commit d9fea9d) in the decoder_context::compute_framedrop_table() function. This vulnerability may cause crashes in applications using this library.

The sort utility in uutils coreutils crashes (panics) when using the --files0-from option with inputs containing non-UTF-8 filenames. The implementation enforces UTF-8 encoding and uses expect(), causing an immediate crash upon encountering valid but non-UTF-8 paths.

The cp utility in uutils coreutils fails to properly handle setuid and setgid bits when ownership preservation fails. When copying with the -p (preserve) flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining original setuid/setgid bits.

An improper access control vulnerability in AMD SEV-SNP allows an admin privileged attacker to write to the RMP during SNP initialization, potentially leading to loss of SEV-SNP guest memory integrity.

The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. It falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID instead of the source's metadata.

A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the mv utility of uutils coreutils during cross-device moves. The extended attribute (xattr) preservation logic uses multiple path-based system calls that perform fresh path-to-inode lookups for each operation. A local attacker with write access can exploit this race condition.

In GraphQL-Ruby before version 2.6.6, when using Execution::Next, authorization failures did not properly halt execution for fields using GraphQL::Schema::Resolver and its subclasses (including Mutation, RelayClassicMutation, and Subscription).

The mongo-go-driver contains a heap out-of-bounds read vulnerability in the CGo implementation for GSSAPI (Kerberos) authentication on Linux and macOS. The issue arises from incorrect assumptions about string termination in the GSSAPI standard, potentially leading to data disclosure.

A TOCTOU vulnerability in the split utility of uutils coreutils allows an attacker to replace the output file between the check and use, potentially leading to data loss. The flaw occurs because the program checks file identity based on paths but later opens the file without re-verification.

The cp utility in uutils coreutils is vulnerable to an information disclosure race condition. Destination files are initially created with umask-derived permissions (e.g., 0644) before being restricted to their final mode (e.g., 0600) later in the process. A local attacker can race to open the file before the permission change.

The 'id' utility in uutils coreutils incorrectly displays data in 'pretty print' mode when the real UID differs from the effective UID. The implementation mistakenly uses the effective GID instead of the effective UID when looking up the name of the effective user, leading to misleading output.

CoreDNS before version 1.14.0 has a vulnerability in gRPC, HTTPS, and HTTP/3 server implementations that lack critical resource-limiting controls. An unauthenticated remote attacker can exhaust memory and degrade or crash the server by opening many concurrent connections.

The vulnerability in IOMMU stems from improper input validation, allowing a malicious hypervisor to reconfigure IOMMU registers. This results in loss of guest data integrity.

An improper access control vulnerability in Secure Encrypted Virtualization (SEV) allows a privileged attacker to write to the reverse map page (RMP) during Secure Nested Paging (SNP) initialization, potentially leading to loss of guest memory confidentiality and integrity.

Missing checks in certain functions related to RMP initialization allow a local admin privileged attacker to cause misidentification of I/O memory, potentially resulting in a loss of guest memory integrity.

In the Linux kernel, a page fault occurs in the vfio/xe driver when resetting VF devices that do not support migration. The fix reorganizes initialization to decouple migration from reset.

A TOCTOU vulnerability in the cp utility of uutils coreutils allows an attacker to bypass the intended no-dereference behavior. The utility checks if a source path is a symbolic link using path-based metadata but subsequently opens it without the O_NOFOLLOW flag.
