A flaw was found in libxml2. Parsing a XML document with the XMLPARSEHUGE option enabled can result in an integer overflow because safety checks were missing in some functions. Also, the xmlParseEntityValue function didn't have any length limitation.
Accessibility. A privacy issue was addressed by removing sensitive data.
A flaw was discovered in the Bluetooth protocol. An attacker within physical proximity to the Bluetooth connection could downgrade the encryption protocol to be trivially brute forced.
A vulnerability affecting Bluetooth BR/EDR pairing was found in the Bluetooth Core specification versions 1.0 through 5.2. The flaw could allow an attacking device to spoof the address of a previously paired remote device to successfully complete the authentication procedure with some paired/bonded devices while not possessing the link key. This can permit an attacker to initiate the Bluetooth Key Negotiation attack (KNOB) on encryption key strength without intervening in an ongoing pairing procedure through an injection attack.
A vulnerability in Bluetooth pairing potentially allows an attacker with physical proximity (within 30 meters) to gain unauthorized access via an adjacent network, intercept traffic and send forged pairing messages between two vulnerable Bluetooth devices. This may result in information disclosure, elevation of privilege and/or denial of service.

A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel.
An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined.

http://seclists.org/oss-sec/2016/q4/602
In SQLite before 3.32.3 select.c mishandles query-flattener optimization leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation.
802.1X. An authentication issue was addressed with improved state management.
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XMLGetCurrentLineNumber (or XMLGetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
libexpat. Multiple issues were addressed by updating to version 2.2.1
Apple Neural Engine. The issue was addressed with improved memory handling.
docorenote in readelf.c in libmagic.a in file 5.35 has an out-of-bounds read because memcpy is misused.
An integer overflow during the parsing of XML using the Expat library.
A privacy issue was addressed with improved access restrictions. This issue is fixed in iOS 27 and iPadOS 27, macOS Golden Gate 27, tvOS 27, visionOS 27, watchOS 27. An app may be able to access sensitive user data.
Accelerate Framework. An out-of-bounds write issue was addressed with improved bounds checking.
A use after free issue was addressed with improved memory management. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, watchOS 27. Processing a maliciously crafted media file may lead to unexpected app termination or corrupt process memory.

A double free issue was addressed with improved memory management. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, watchOS 27. An app may be able to cause unexpected system termination.
A specially-crafted file can cause libjxl's decoder to write pixel data to uninitialized unallocated memory. Soon after that data from another uninitialized unallocated region is copied to pixel data.
This can be done by requesting color transformation of grayscale images to another grayscale color space. Buffers allocated for 1-float-per-pixel are used as if they are allocated for 3-float-per-pixel. That happens only if LCMS2 is used as CMS engine. There is another CMS engine available (selected by build flags).
A buffer overflow was addressed with improved bounds checking. This issue is fixed in iOS 18.7.9 and iPadOS 18.7.9, iOS 26.5 and iPadOS 26.5, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5, tvOS 26.5, visionOS 26.5, watchOS 26.5. A remote attacker may be able to cause unexpected app termination.
Accelerate. An out-of-bounds read was addressed with improved bounds checking.
A race condition was addressed with additional validation. This issue is fixed in iOS 18.7.10 and iPadOS 18.7.10, iOS 26.5 and iPadOS 26.5, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5, tvOS 26.5, visionOS 26.5, watchOS 26.5. An app may be able to access sensitive user data.
