CVE-2026-98007

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject non-scalar bpfloop iteration counts bpfloop declares its nrloops argument as ARGANYTHING. Privileged programs may pass pointer values to such arguments, so checkfuncarg lets a pointer-valued R1 reach the helper-specif...

CVE-2026-81687: Uncontrolled Resource Consumption

opensslencrypt versions before 1.4.9 fail to enforce a time ceiling on key derivation function iteration counts specified in file metadata. Attackers can craft files with extremely high KDF iteration counts to consume CPU resources for unbounded periods before password verification occurs...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in PKCS12KeyStoreSpi, which feeds the attacker-controlled KDF iteration count from a PKCS12 file's MAC data and encrypted bags into key derivation during engineLoad without enforcing...

CVE-2026-11790

The CVE-2026-11790 entry describes a vulnerability in 389 Directory Server’s PBKDF2-SHA256 password storage plugin where there is no upper bound on the iteration count extracted from stored password hashes. A privileged attacker who can modify a user’s password hash can trigger excessive CPU usag...

PT-2026-47780

Name of the Vulnerable Software and Affected Versions 389 Directory Server affected versions not specified Description A flaw exists in the PBKDF2-SHA256 password storage plugin where the system fails to enforce an upper bound on the iteration count extracted from stored password hashes. A...

NLnet Labs Unbound 安全漏洞

NLnet Labs Unbound is a high-performance DNS resolver open-sourced by NLnet Labs. Versions of NLnet Labs Unbound 1.25.0 and earlier contained security vulnerabilities. These vulnerabilities stemmed from the DNSSEC verifier failing to account for NSEC3 hash calculation restrictions when querying D...

DEBIAN-CVE-2026-42256

Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. From versions 0.4.0 to before 0.4.24, 0.5.0 to before 0.5.14, and 0.6.0 to before 0.6.4, when authenticating a connection with SCRAM-SHA1 or SCRAM-SHA256, a hostile server can perform a computational...

net-imap vulnerable to denial of service via high iteration count for `SCRAM-*` authentication

Summary When authenticating a connection with SCRAM-SHA1 or SCRAM-SHA256, a hostile server can perform a computational denial-of-service attack on the client process by sending a big iteration count value. Details A hostile IMAP server can send an arbitrarily large PBKDF2 iteration count in the...

jose4j: denial of service via specially crafted JWE

A flaw was found in the jose.4.j jose4j library. The JWE key management algorithms based on PBKDF2 require a JOSE Header Parameter called p2c PBES2 Count. This parameter dictates the number of PBKDF2 iterations needed to derive a CEK wrapping key. Its primary purpose is to intentionally slow down...
