CVE-2026-129115	Unknown	2026-11-14	Not applicable	No public exploit	JSON::XS versions from 3.0 before 4.05 for Perl read freed stack memory when a FREEZE result's serialisation grows the Perl stack under allow_tags in encode_rv. With allow_tags, an object's FREEZE method is called in list context and each returned value is encoded through a saved Perl stack pointer. When encoding a returned value calls back into Perl, through TO_JSON under convert_blessed or another FREEZE, and that callback grows the stack, the stack is reallocated while the saved pointer still refers to the freed block. Encoding such objects reads freed memory, and encode can return undef without an error.
CVE-2026-15465	Unknown	2026-11-13	Not applicable	No public exploit	Software installed and run as a non-privileged user may conduct improper GPU system calls through the DDK kernel module interface. Under unsupported use of the interface, a use-after-free condition may occur that can lead to kernel memory corruption, platform instability, or system reboot. The weakness occurs when software references memory after it has been released. Accessing memory after free may result in corruption of valid data structures, unexpected program behaviour, process crashes, or execution of unintended operations.
CVE-2026-95691	Unknown	2026-11-10	Not applicable	No public exploit	Issue summary: A retransmitted QUIC CRYPTO frame can release packet storage while the TLS record layer retains a direct pointer into that storage causing use after free. Impact summary: A malicious QUIC server can cause a heap-use-after-free read in the OpenSSL QUIC client. The server can also identify one allocator-adjacent byte through the client's protected Handshake response. CWE: CWE-416: Use After Free Description: During CRYPTO stream processing, a pointer into the first frame's memory on the stream is lent to the TLS handshake processing. The memory must remain stable until it is processed and released. However the processing of retransmitted CRYPTO frames could release the memory if the retransmitted frame fully overlapped the existing frame. This then causes use-after-free read when the TLS handshake processing continues. The use-after-free read can lead to a Denial-of-Service of the client application or a minor leak of information about the heap memory contents that might be overwritten with other data, subsequently allocated by the application, to the peer. FIPS impact: no The FIPS module is not affected as the QUIC implementation is outside of the OpenSSL FIPS module boundary.
