Race Condition in Symbolic Link Handling Allows Modification of Protected File System Parts

A race condition was addressed with improved handling of symbolic links. This issue is fixed in macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2. An app may be able to modify protected parts of the file system.

A malformed Session header permanently orphans one packet-pool block per RTSP request

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, the RTSP server returns a raw parser error for a malformed Session header and never releases the response packet it allocated. An unauthenticated client can drain the server's packet pool with a few dozen requests, stopping the RTSP server and, where the pool is shared, the rest of the network stack until the device restarts.

ICMPv6 option validation accepts a trailing byte residue, sending the Router Advertisement, Neighbor Solicitation, Neighbor Advertisement and Redirect option walkers past the packet or into a permanent loop

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, built with IPv6, the ICMPv6 option validator accepts an option area that ends in a one- or two-byte residue, and the Router Advertisement, Neighbor Solicitation, Neighbor Advertisement and Redirect handlers then walk it without length checks. A host on the local link can send one such message to make the IP thread read past the packet or loop forever, and can place off-packet memory in the neighbor cache.

Unbounded DATA datagram in the NetX Duo TFTP server causes an out-of-bounds read and a permanent stall

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, built with packet chaining, the TFTP server does not bound the length of a received DATA datagram. An unauthenticated peer can upload an oversized datagram that writes memory beyond the received packet into the file and read it back by downloading the file, and the same datagram can suspend the server thread permanently.
