kernel: net: sched: act_csum: validate nested VLAN headers

A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...

CVE-2026-64513

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for x86 architectures. When the apicupdateppr function does not find a deliverable interrupt, it fails to recompute the CR8 intercept, leading to a stale Task Priority Register Threshold TPRTHRESHOLD. This issue can cause a...

PT-2026-66566

Uncontrolled recursion in the unknown-key skip path of the aws-smithy-json runtime crate before 0.62.7, which the smithy-rs code generator invokes from every generated struct deserializer, might allow remote unauthenticated users to cause a denial of service process abort via stack exhaustion via...

axios: axios: Denial of Service via uncontrolled recursion in form data processing

A flaw was found in axios, a popular JavaScript library. An attacker can exploit this vulnerability by providing malicious form data containing deeply nested field names. This input triggers uncontrolled recursion within the formDataToJSON function, which is responsible for processing form data...

CVE-2026-67216

A flaw was found in cJSON. An inefficient algorithmic complexity flaw in the cJSONCompare function allows a remote attacker to cause a denial of service DoS. By providing specially crafted, deeply nested JSON JavaScript Object Notation objects for comparison, an attacker can consume excessive CPU...

CVE-2026-64308

A flaw was found in the Linux kernel's crypto: ccp module, which handles AMD Secure Encrypted Virtualization SEV and Secure Nested Paging SNP features. A local user, by sending specific commands through the /dev/sev interface, could exploit improper initialization handling. If SEV initialization...

CVE-2026-67194

Courier IMAP before 6.0.1 and Courier Mail Server before 2.0.2 allow authenticated IMAP users to crash the imapd process via deeply nested parenthesized SEARCH queries. The SEARCH command parser allocsearchkey in searchinfo.C recursively descends on nested parenthesized groups through a mutual...

CVE-2026-67194

CVE-2026-67194 affects Courier IMAP prior to 6.0.1 and Courier Mail Server prior to 2.0.2. The vulnerability lies in the SEARCH parser (alloc_search_key in searchinfo.C), which recursively descends through deeply nested parenthesized groups without a depth limit. A single IMAP command with ~2500 ...

CVE-2026-67216

cJSON through 1.7.19 contains an inefficient algorithmic complexity flaw in cJSONCompare. When comparing objects, the function recurses into each shared subtree twice, once in each direction, with no depth guard, making the running time exponential in nesting depth. A small, deeply nested documen...

CVE-2026-64288

A flaw was found in the kernel's Kernel-based Virtual Machine KVM component for ARM64 architectures. A race condition can occur during the invalidation of the virtual Nested Translation Cache VNCR pseudo-TLB when a virtual CPU vcpu is being brought online or offline. This can lead to a null point...
