CVE Vulnerability Catalog

In the Linux kernel, a vulnerability was found in the mechanism preventing timer interrupt starvation. Missing resets of the next_event_forced flag in several places, such as when the clock event state changes, may cause incorrect behavior.

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 libfuse versions 3.18.0 through 3.18.1 causes a NULL pointer dereference and memory leak in the fuse_uring_init_queue function. A local user can exploit this to crash the FUSE daemon or exhaust system resources.

The vulnerability in the Nokogiri library affects the `Nokogiri::XML::Node#do_xinclude` method, which during XInclude processing removes `<xi:include>` nodes along with their children (e.g., `<xi:fallback>`) and declared namespaces. If an application previously accessed these nodes, unexpected behavior may occur.

An issue was discovered in shadow 4.5. newgidmap (in shadow-utils) is setuid and allows an unprivileged user to be placed in a user namespace where setgroups(2) is permitted. This allows an attacker to remove themselves from a supplementary group, which may allow access to certain filesystem paths.

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 vulnerability in the Nokogiri library allows a DTD node to be set as the document root, leading to a heap use-after-free during garbage collection or finalization. This results in an invalid memory read or potentially a segfault.

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.

Insufficient checks of the RMP on host buffer access in IOMMU may allow an attacker with privileges and a compromised hypervisor to trigger an out of bounds condition without RMP checks, resulting in a potential loss of confidential guest integrity.

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.

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 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.

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 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 golang.org/x/crypto/openpgp package is unsafe by design, has numerous known security issues, is not maintained, and should not be used. It is recommended to use the maintained package github.com/ProtonMail/go-crypto/openpgp instead.

Nokogiri's CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an XML attribute. If Ruby code had already accessed an attribute child node, `Nokogiri::XML::Attr#value=` could free the underlying native child node while the wrapper remains.

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.
