CVE Vulnerability Catalog

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.

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 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.

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 Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting its contents.

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 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.

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.

In NTFS-3G through version 2026.2.25, a heap buffer overflow exists in the ntfs_ir_to_ib() function in index.c. An attacker can exploit this by crafting a malicious NTFS image that, when mounted and a directory is extended (e.g., by creating a file), corrupts heap memory in the SUID-root ntfs-3g binary.

In NTFS-3G through version 2026.2.25, a heap buffer overflow exists in the cat() function in cat.c. An attacker can exploit this by crafting a malicious NTFS image that, when a file is read, corrupts heap memory in the ntfscat binary.

A logic error in the `ln` utility of uutils coreutils causes the program to reject source paths containing non-UTF-8 filename bytes when using target-directory forms (e.g., `ln SOURCE... DIRECTORY`). While GNU ln treats filenames as raw bytes and creates links correctly, the uutils implementation enforces UTF-8 encoding.

The html.Parse function in the golang.org/x/net/html package enters an infinite loop when processing specially crafted HTML input. An attacker can exploit this vulnerability to cause a denial of service (DoS).

The 'id' utility in uutils coreutils miscalculates the 'groups=' section of its output. The implementation uses the user's real GID instead of their effective GID to compute the group list, leading to potentially divergent output compared to GNU coreutils.

A vulnerability in the rm utility of uutils coreutils allows bypassing safeguards that protect the current directory. The utility correctly refuses to delete . or .., but fails to recognize equivalent paths with trailing slashes, such as ./ or .///.

The touch utility in uutils coreutils is vulnerable to a TOCTOU race condition during file creation. After identifying a missing path, the utility later attempts creation using File::create(), which internally uses O_TRUNC. An attacker can exploit this window to create a file.

The email module in Python, specifically the BytesGenerator class, improperly quotes newlines in email headers during serialization, allowing header injection. This only affects usage of LiteralHeader that does not respect email folding.

An improper initialization vulnerability in the AMD Secure Encrypted Virtualization (SEV) firmware allows an admin-privileged attacker to corrupt RMP-covered memory, potentially leading to loss of guest memory integrity.

A Time-of-Check to Time-of-Use (TOCTOU) race condition exists in the mv utility of uutils coreutils during cross-device operations. The utility removes the destination path before recreating it through a copy operation, which a local attacker with write access to the destination directory can exploit.

The nohup utility in uutils coreutils creates its default output file, nohup.out, without specifying explicit restricted permissions. This causes the file to inherit umask-based permissions, typically resulting in a world-readable file (0644).

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.

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.
