CVE Vulnerability Catalog

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).

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.

A vulnerability in the DNS protocol, related to the Closest Encloser Proof aspect in RFC 5155 (when RFC 9276 guidance is skipped), allows remote attackers to cause a denial of service (DoS) by triggering excessive CPU consumption for SHA-1 computations. The attack involves sending DNSSEC responses in a random subdomain attack, known as the NSEC3 issue.

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.

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.

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.

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 .///.

In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, when using PHP-FPM SAPI with catch_workers_output = yes, it may be possible to pollute the final log or remove up to 4 characters from log messages by manipulating the log message.

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 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.

In the Linux kernel, the bnge driver has a vulnerability where a return statement is missing after auxiliary_device_uninit() in the error path. After auxiliary_device_add() fails, execution continues, potentially leading to use-after-free.

A use-after-free vulnerability was found in the QEMU LSI53C895A SCSI Host Bus Adapter emulation. This issue can lead to a crash or VM escape.

No description is available for CVE-2026-6502. The nature of the vulnerability cannot be determined.

A divide-by-zero error was discovered in py-lmdb 0.97 in the mdb_env_open2 function when mdb_env_read_header obtains a zero value for a certain size field. This issue can be triggered by supplying a crafted data.mdb file.

In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, uncontrolled long string inputs to the ldap_escape() function on 32-bit systems can cause an integer overflow, resulting in an out-of-bounds write.

In GNU C Library versions 2.27 to 2.38, an untrusted LD_LIBRARY_PATH environment variable vulnerability allows attacker-controlled loading of dynamically shared libraries in statically compiled setuid binaries that call dlopen (including internal dlopen calls after setlocale or calls to NSS functions).

A floating-point exception in the PSStack::roll function of Poppler before 25.04.0 can cause application crashes when handling malformed inputs associated with INT_MIN.

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.

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.
