kernel: tipc: fix double-free in tipc_buf_append()

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...

kernel: netfilter: conntrack: remove sprintf usage

A flaw was found in the Linux kernel's netfilter conntrack module. This vulnerability arises from the use of sprintf and insufficient buffer sizing in the manglecontentlen function, which can lead to a stack-out-of-bounds write. An attacker could potentially exploit this memory corruption issue t...

kernel: xfrm: fix stale skb->prev after async crypto steals a GSO segment

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...

kernel: s390/pkey: Check length in pkey_pckmo handler implementation

A flaw was found in the Linux kernel, specifically within the s390/pkey component. This vulnerability occurs because the pkeypckmo handler function does not explicitly check the length of the target buffer. If the generated output data exceeds the provided buffer's length, the handler function...

kernel: xfrm: hold dev ref until after transport_finish NF_HOOK

A flaw was found in the Linux kernel's xfrm IP eXtensible FRamework subsystem. This vulnerability involves a race condition where a network device's reference is released too early during packet processing after asynchronous cryptography. This premature release can lead to the system attempting t...

kernel: ip6: vti: Use ip6_tnl.net in vti6_changelink()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface vti6 component. An unprivileged local user, particularly within a user namespace, could exploit a vulnerability related to incorrect network namespace handling during the movement of a vti6 tunnel. This issue can lead to a kerne...

kernel: net: pull headers in qdisc_pkt_len_segs_init()

A flaw was found in the Linux kernel's handling of Generic Segmentation Offload GSO packet headers. This vulnerability occurs when the qdiscpktlensegsinit function does not properly pull headers into the expected memory location, which can lead to incorrect processing by network drivers. A remote...

kernel: ip6: vti: Use ip6_tnl.net in vti6_siocdevprivate()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface VTI module. When a VTI tunnel device is moved to a different network environment, an unprivileged user in a separate user space can manipulate tunnel parameters. This manipulation could allow the user to intercept or redirect...

CVE-2026-86095

A flaw was found in netcdf-c. An attacker can craft a malicious HDF5 Hierarchical Data Format 5 file with an oversized attribute name. When an application processes this file and attempts to enumerate attribute names, the oversized name can cause an out-of-bounds write, leading to memory corrupti...

Uncontrolled Resource Consumption

Apache Qpid ProtonJ2 is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to the lack of a limit on the number of transfer frames per incoming delivery, which allows an authenticated attacker to cause excessive resource consumption and potentially trigger a denial-of-servi...

EUVD-2026-90662

Ghost versions before 6.62.0 contain an authentication bypass vulnerability that allows suspended staff users to reactivate their accounts through self-service password reset. Attackers with suspended staff credentials can perform password reset operations to regain active account access and...

CVE-2026-103261 Tornado before 6.5.9 Denial of Service via Query String

Tornado before 6.5.9 fails to limit the number of query string fields in HTTPServerRequest.init, allowing remote attackers to cause event-loop stalling by sending requests with thousands of query parameters. Attackers can send unauthenticated GET requests with unbounded query-string field counts ...

CVE-2026-103262 Tornado before 6.5.9 Denial of Service via CurlAsyncHTTPClient

Tornado versions before 6.5.9 contain an unbounded memory accumulation vulnerability in CurlAsyncHTTPClient that allows remote attackers to cause denial of service by sending a compressed response. Attackers can send a gzip-encoded decompression bomb that accumulates in memory without size limits...

EUVD-2026-90656

Tornado versions before 6.5.9 contain an unbounded memory accumulation vulnerability in CurlAsyncHTTPClient that allows remote attackers to cause denial of service by sending a compressed response. Attackers can send a gzip-encoded decompression bomb that accumulates in memory without size limits...

CVE-2026-103262 Tornado before 6.5.9 Denial of Service via CurlAsyncHTTPClient

Tornado versions before 6.5.9 contain an unbounded memory accumulation vulnerability in CurlAsyncHTTPClient that allows remote attackers to cause denial of service by sending a compressed response. Attackers can send a gzip-encoded decompression bomb that accumulates in memory without size limits...

CVE-2026-103261

The Tornado web framework versions prior to 6.5.9 are vulnerable to a Denial of Service (DoS) condition. The root cause is a lack of limits on the number of query string fields processed within the HTTPServerRequest.__init__ component. A remote, unauthenticated attacker can exploit this by sendin...

CVE-2026-103262

Tornado versions before 6.5.9 are vulnerable to a Denial of Service (DoS) attack via the CurlAsyncHTTPClient component. The root cause is an unbounded memory accumulation vulnerability where the client fails to enforce limits on incoming response sizes. A remote malicious server can exploit this ...

Resource Exhaustion

Apache Qpid ProtonJ2 is vulnerable to resource exhaustion. The vulnerability is due to unbounded symbol value caching, where symbol values are cached without size limits and a pre-authentication attacker can send crafted input to exhaust resources, leading to denial of service...

Uncontrolled Resource Consumption

Apache Qpid Broker-J is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to unbounded caching of symbol values, which allows a pre-authentication attacker to exhaust server resources and cause a denial-of-service condition...
