CVE Vulnerability Catalog

A vulnerability has been identified in the Linux kernel related to improper reference counting management in the 'xfrm_state' structure. The issue occurs during the NETDEV_UNREGISTER event, leading to reference count leaks.

The ifconfig command in Linux kernel 2.2 and later does not report when the network interface is in promiscuous mode if it was enabled using PACKET_MR_PROMISC. This could allow attackers to sniff network traffic undetected.

A vulnerability in the Linux kernel related to vhost has been resolved by moving the vdpa group bound check to vhost_vdpa. This reduces duplication and lowers the risk of a parent driver missing them.

A vulnerability has been identified in the Linux kernel within the rockchip module that may lead to ERR_PTR dereference in the rga_buf_init() function. The issue occurs when rga_get_frame() returns ERR_PTR(-EINVAL) due to an unsupported or invalid buffer type.

Sigstore Timestamp Authority is a service for issuing RFC 3161 timestamps. Versions 2.0.5 and below contain an authorization bypass vulnerability in the VerifyTimestampResponse function.

A vulnerability has been identified in the Linux kernel within the ALSA usb-audio module, concerning the lack of size verification for URB packets during playback silencing. This issue may lead to uncontrolled writes outside the allocated buffer.

A vulnerability in the XML::Parser library for Perl (up to version 2.45) causes a heap buffer overflow, leading to double free or corruption and crashes. The issue occurs in the parse_stream() function in Expat.xs when the :utf8 PerlIO layer is used, because Perl returns decoded characters while SvPV() expects raw bytes.

Sudo VISudo version 1.6.8 and earlier allows local users to corrupt arbitrary files via a symlink attack on temporary files.

An issue was discovered in py-lmdb 0.97 where mdb_node_del does not validate a memmove in the case of an unexpected node->mn_hi, leading to an invalid write operation. This occurs when accessing a data.mdb file supplied by an attacker.

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.

When curl is asked to use a `.netrc` file for credentials and to follow HTTP redirects, it could leak the password used for the first host to the followed-to host under certain circumstances. This flaw only manifests if the netrc file has an entry matching the redirect target hostname.

runc 1.1.13 and earlier, as well as 1.2.0-rc2 and earlier, can be tricked into creating empty files or directories in arbitrary locations in the host filesystem by sharing a volume between two containers and exploiting certain operations.

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.

An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This could cause a denial of service.

When curl is told to use the Certificate Status Request TLS extension (OCSP stapling) to verify the server certificate, it might fail to detect some OCSP problems and wrongly consider the response as fine if the returned status reports another error than expected.

When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache entry, making it end sooner or later than otherwise intended. This affects applications using HSTS and URLs with the insecure HTTP:// scheme.

Git defines a line-based protocol used to exchange information between Git and Git credential helpers. Some ecosystems (most likely those using this protocol) may be vulnerable to attacks related to this protocol.

A vulnerability in TLS 1.3 with certificate compression can force a large buffer allocation before decompression without checking the configured certificate size limit. An attacker can cause per-connection memory allocations of up to approximately 22 MiB.

If an application using the `SSL_CIPHER_find()` function in a QUIC protocol client or server receives an unknown cipher suite from the peer, a NULL dereference occurs. This leads to abnormal termination of the running process, causing Denial of Service (DoS).

An out-of-bounds write vulnerability was found in glibc before version 2.31 when handling signal trampolines on PowerPC. The backtrace function did not properly check array bounds when storing the frame address, leading to denial of service or potential code execution.
