CVE Vulnerability Catalog

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.

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.

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 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.

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.

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 Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting its contents.

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.

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.

An issue was discovered in py-lmdb 0.97 where mdb_page_touch does not properly set up mc->mc_pg[mc->top] for certain mp_flags values, leading to an invalid write operation. The vulnerability can be triggered by supplying a crafted data.mdb file.

A vulnerability in SEV (Secure Encrypted Virtualization) firmware causes insufficient or incomplete data removal in a hardware component, resulting in incomplete IOMMU flushing. This can potentially lead to a loss of confidentiality and integrity in guest memory.

In the Linux kernel, a vulnerability was found in the F2FS filesystem involving uninitialized value access in the f2fs_sanity_check_node_footer function. The issue was reported by syzbot and may lead to unpredictable system behavior.

A use-after-free vulnerability in SEV firmware allows a malicious hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent, potentially leading to loss of integrity.

In the Linux kernel, a vulnerability in the mshv_vtl component occurs when registering VTL0 memory via MSHV_ADD_VTL0_MEMORY, where the computed vmemmap_shift may exceed MAX_FOLIO_ORDER, leading to incorrect behavior.

A vulnerability in the Linux kernel's FUSE filesystem causes a hang during sync initialization when the FUSE server exits (e.g., due to error or crash) while processing the FUSE_INIT request. The issue stems from the lack of abort on a fatal signal, blocking filesystem creation.

A vulnerability in SEV (Secure Encrypted Virtualization) firmware allows a privileged attacker to modify the lock bit, potentially downgrading the firmware and compromising system integrity.

A vulnerability in the UEFI implementation within QEMU (or similar software) causes a heap overflow in the hardware module (hw/uefi). An attacker can exploit this flaw to gain unauthorized access or execute arbitrary code.

Insufficient granularity of access control in SEV firmware allows a privileged user with a malicious hypervisor to create a SEV-ES guest with an ASID meant for SEV-SNP guests, potentially leading to partial loss of confidentiality.

A vulnerability in the Nokogiri library affects the `Nokogiri::XML::NodeSet#[]` method (and its alias `#slice`). The index check against the node set's bounds used a 32-bit-truncated copy of the index, allowing a large negative index to pass the check and then be used at full width, reading outside the node set's storage.

A NULL pointer dereference vulnerability was found in the Linux kernel's ALSA driver for the TASCAM US-144MKII device. A malicious USB device can have a configuration with interface number 1 but missing interface 0, leading to a system crash.

An issue was discovered in py-lmdb 0.97 where for certain values of mn_flags, mdb_cursor_set triggers a memcpy with an invalid write operation within mdb_xcursor_init1. This occurs when accessing a data.mdb file supplied by an attacker.
