CVE-2026-54284 sqlparse: TokenList.__init__ materializes O(subtree) value per group, causing CPU DoS before depth/token caps trigger

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, TokenList construction and string conversion in sqlparse/sql.py repeatedly flatten nested token subtrees constructed by groupparenthesis and groupcase, causing quadratic CPU consumption through sqlparse.parse,...

CVE-2026-54284

sqlparse versions before 0.6.0 have a CPU DoS flaw: TokenList.__init__ calls str(self), which recursively flattens the entire subtree on every group construction, producing O(n*d) cost. A ~2 KB deeply-nested SQL payload pins a worker for ~10 seconds (~5000x amplification). Flask-based SQL formatt...

CVE-2026-59881

A flaw was found in AIOHTTP. The WebSocket client in AIOHTTP processes compressed data frames even when the compression mechanism, known as permessage-deflate, has not been properly negotiated. A malicious server can exploit this by sending specially crafted compressed frames. This can lead to...

CVE-2026-72016

A flaw was found in the Linux kernel's CPU hotplug mechanism on arm64 systems. When a system is booted with more maximum CPUs configured than are physically present, some CPUs are incorrectly marked as present but are not fully registered. This can lead to a kernel warning due to a null kobject...

BIT-PYTHON-MIN-2026-18503 Super-linear CPU usage for unbounded input to csv.Sniffer.sniff()

Attacker-controlled CSV samples can trigger super-linear regular-expression work during dialect sniffing and consume significant CPU when applications pass unbounded input to csv.Sniffer.sniff...

kernel: xen: AMD Zen 2 Processors: Privilege escalation via improper CPU cache isolation

A flaw was found in AMD Zen 2-based processors, affecting components such as the kernel and Xen hypervisor. Improper isolation of shared resources within the CPU operation cache could allow an attacker to corrupt instructions executed at a different privilege level. This could potentially result ...

Important: perl-Date-Manip

Issue Overview: Date::Manip versions through 6.99 for Perl return corrupted dates via non-ASCII decimal digits that pass the numeric range tests in check. The parse regexes capture year, month and day with the \d shorthand, which on a character string matches the whole Unicode decimal digit...

CVE-2026-74797
