grafana: grafana: Authorization bypass via missing destination folder permission check

A flaw was found in Grafana. The application fails to verify creation permissions on destination folders during panel update operations. An authenticated user with edit permissions in one folder can exploit this vulnerability through the library elements API to move a library panel into a folder...

grafana: grafana: Information disclosure via unrevoked access tokens in paused shared dashboards

A flaw was found in Grafana. This vulnerability allows information disclosure because pausing a shared dashboard fails to revoke access tokens for endpoints serving initialization data. An unauthenticated remote attacker possessing the link to a paused dashboard can exploit this flaw to retrieve...

openssl: openssl: Denial of Service via inefficient QUIC stream reassembly

A flaw was found in OpenSSL. A remote attacker who establishes a QUIC network connection can cause a Denial of Service DoS by sending specially sequenced, out-of-order stream frames. Because the stream reassembly mechanism handles non-sequential data fragments inefficiently, processing these fram...

openssl: openssl: Denial of Service via excessive QUIC packet buffer retention

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by sending specially crafted network packets to a QUIC protocol endpoint. Because the QUIC stack retains memory in packet buffers until the receiving application reads the stream data, an attacker can manipulate data...

openssl: openssl: Denial of Service via excessive memory allocation in CRL distribution point processing

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by presenting a specially crafted certificate during a Transport Layer Security TLS handshake. When OpenSSL processes and caches certificate extensions containing numerous Certificate Revocation List CRL distribution...

openssl: openssl: Denial of Service via out-of-bounds write during TLS context switch

A flaw was found in openssl. When a server replaces its security context during an active Transport Layer Security TLS handshake, it fails to update the internal capacity tracking for cryptographic signature algorithms. A remote peer can exploit this issue by advertising specific signature...

openssl: OpenSSL: Denial of Service via unbounded QUIC connection identifier backlog

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by flooding a connection with connection identifier update requests while withholding acknowledgments. This behavior bypasses connection limits and forces the system to accumulate pending retirement frames, resulting...

openssl: openssl: Denial of Service via crafted CMP certificate revocation response

A flaw was found in OpenSSL. When a Certificate Management Protocol CMP client requests certificate revocation using a PKCS10 Certificate Signing Request CSR, it omits the certificate issuer name and serial number. A malicious or compromised CMP server, or an attacker possessing valid message...

openssl: OpenSSL: Denial of Service via undersized DTLS record

A flaw was found in OpenSSL. A remote, unauthenticated attacker can cause a Denial of Service DoS by terminating an active Datagram Transport Layer Security DTLS session. By sending an undersized network packet that is shorter than the expected cryptographic overhead, the record processing layer...

brace-expansion: brace-expansion: Denial of Service via stack exhaustion from crafted brace patterns

A flaw was found in brace-expansion. A remote attacker can provide specially crafted brace patterns with excessive nested groups or large arrays to trigger uncontrolled recursion during parsing. This behavior exhausts the native call stack and crashes the application process, leading to a Denial ...

brace-expansion: brace-expansion: Denial of Service via uncontrolled recursion in nested brace patterns

A flaw was found in brace-expansion. A remote attacker can cause a Denial of Service DoS by supplying untrusted input containing deeply nested brace patterns. Due to uncontrolled recursion during pattern processing, expanding these nested structures exhausts the call stack and causes the...

brace-expansion: brace-expansion: Denial of Service via crafted brace patterns

A flaw was found in brace-expansion. A remote attacker can cause a Denial of Service DoS by supplying specially crafted string patterns with repeated closing braces. Processing these malformed patterns causes the string expansion logic to repeatedly rescan the entire input, leading to excessive...

python: Python: CPU Denial of Service in HTML parser via repeated unterminated markup declarations

A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit CPU resources. This leads to...

kernel: dm-integrity: don't increment hash_offset twice

A flaw was found in the dm-integrity component of the Linux kernel. This vulnerability arises from an error where a hashoffset variable is incremented twice, leading to incorrect memory access. A local attacker could exploit this issue to trigger a system crash, resulting in a denial of service...

CVE-2026-101283

iperf3 3.20–3.21 esnet/iperf has a pre-auth heap buffer overflow in decryptrsamessage: a 256-byte RSA buffer is BIOread with the attacker-controlled ciphertext length guard warns only, so an unauthenticated client overflows the heap via an oversized authtoken; fixed in 3.22...

iperf3 3.20–3.21 esnet/iperf has a pre-auth heap buffer overflow in decryptrsamessage: a 256-byte RSA buffer is BIOread with the attacker-controlled ciphertext length guard warns only, so an unauthenticated client overflows the heap via an oversized authtoken; fixed in 3.22...

python: Quadratic complexity in os.path.expandvars() with user-controlled template

A vulnerability in Python’s os.path.expandvars function that can cause performance degradation. When processing specially crafted, user-controlled input with nested environment variable patterns, the function exhibits quadratic time complexity, potentially leading to excessive CPU usage and denia...

cpython: Python HTMLParser quadratic complexity

A denial-of-service DoS vulnerability has been discovered in Python's html.parser.HTMLParser class. When processing specially malformed HTML input, the parsing runtime can become quadratic with respect to the input size. This significantly increased processing time can lead to excessive resource...

python: cpython: CPython: tarfile extraction filter bypass allows escaping the destination directory

A flaw was found in the tarfile.extractall function within Python. A remote attacker could exploit this vulnerability by providing a specially crafted archive. This archive could bypass security filters by using a hardlink that references a symlink, allowing the symlink to be recreated outside th...

rsync: rsync: Unauthorized File Access via Symlink Module Root

A flaw was found in rsync. This path traversal vulnerability allows remote clients to access files outside the intended module root. This occurs when the use chroot option is disabled and the module root path, or a component of it, is a symbolic link. The rsync daemon fails to resolve symlinks...
