CVE-2026-15465

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...

CVE-2026-16671

The MCUboot bootloader contains an out-of-bounds stack write in the split_image_check() function located in boot/bootutil/src/loader.c. The vulnerability occurs because a fixed 32-byte buffer (loader_hash) is used to store image hashes, but the bootutil_img_validate() routine copies IMAGE_HASH_SI...

kernel: i3c: master: svc: bound IBI payload to the requested max_payload_len

A flaw was found in the Linux kernel's I3C master driver. A malicious I3C device could exploit this by sending an In-Band Interrupt IBI payload that exceeds the allocated slot size. This can lead to an out-of-bounds write into the IBI pool, potentially causing memory corruption and system...

kernel: sunrpc: wait for in-flight TLS handshake callback when cancel loses race

A flaw was found in the kernel. A race condition exists in the sunrpc component during the Transport Layer Security TLS handshake cancellation process. This can lead to the corruption of an internal data structure, potentially causing system instability or a denial of service. Additionally, it ma...

gcc: libstdc++ integer overflow in `new` operator

A flaw was found in libstdc++. An integer overflow can occur when processing large inputs to the aligned operator new in the C++ library. This vulnerability could lead to an undersized memory allocation, potentially causing memory corruption or application instability...

kernel: af_unix: Unlink scc_entry in unix_del_edge()

A flaw was found in the Linux kernel's afunix component. A race condition during concurrent send and close operations can lead to the garbage collector GC partially freeing a Strongly Connected Component SCC. This inconsistent state may cause subsequent GC operations to iterate over a partially...

kernel: net/sched: act_api: use RCU with deferred freeing for action lifecycle

A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free UAF vulnerability,...

kernel: Bluetooth: hci_sync: Fix advertising data UAFs

A flaw was found in the Linux kernel's Bluetooth subsystem. Specifically, the hcisync component, which manages Bluetooth advertising data, is susceptible to a Use-After-Free UAF vulnerability. This occurs when a pointer to advertising data becomes invalid but is still accessed, particularly durin...

kernel: virt: tdx-guest: Just leak decrypted memory on unrecoverable errors

A flaw was found in the Linux kernel's Intel Trust Domain Extensions TDX guest driver used in confidential computing virtual machines. An untrusted host hypervisor can induce unrecoverable errors during memory decryption, causing the guest kernel to return shared, unencrypted memory back into the...

kernel: nfsd: don't free session slots that are still in use

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. A remote attacker could exploit a use-after-free vulnerability in the nfsd4sequence function. This occurs when the system attempts to reduce the number of active session slots while a client is still using one of the slo...

kernel: drm/amdgpu/vce: fix integer overflow in image size

A flaw was found in the drm/amdgpu/vce component of the Linux kernel. Malicious VCE Video Codec Engine command streams with oversized dimensions can cause a 32-bit integer overflow. This overflow bypasses validation, allowing the GPU firmware to perform out-of-bound memory access. This could lead...

kernel: nfsd: revoke copy-notify stateids before dropping their reference

A flaw was found in the Linux kernel's Network File System Daemon nfsd. This vulnerability arises from improper handling of "copy-notify stateids" during their revocation. When a stateid's reference is dropped without unlinking it, the memory can be freed while still in use by a reader, leading t...

kernel: nfsd: fix UAF in async copy cancel and shutdown

A flaw was found in the Linux kernel's nfsd component. A race condition exists during asynchronous copy cancellation and shutdown operations, which can lead to a Use-After-Free UAF vulnerability. This allows an async copy object to be freed or used after being freed, potentially causing memory...

kernel: ipvs: do not propagate one-packet flag to synced conns

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When a synced connection is established, it can incorrectly inherit a "one-packet" flag from its destination. This misconfiguration causes the connection's expiry process to mishandle its cleanup, leaving behind stale memory...

kernel: netfilter: nf_queue: pin bridge device while NFQUEUE holds fake dst

A flaw was found in the Linux kernel's netfilter component, specifically within the nfqueue functionality. When a bridged packet is queued to NFQUEUE, it can retain a reference to a bridge's private fake destination 'dst' even after the bridge teardown has begun. This can lead to a use-after-free...

kernel: Revert "net/smc: Introduce TCP ULP support"

A flaw was found in the Linux kernel's TCP User-Level Protocol ULP support for SMC. This vulnerability arises when an active TCP socket is converted into an SMC socket, as the implementation attempts to modify core Virtual File System VFS structures in-place. This action violates fundamental VFS...

kernel: Linux kernel: PPP over L2TP Use-After-Free vulnerability

A flaw was found in the Linux kernel's Point-to-Point Protocol PPP over L2TP Layer 2 Tunneling Protocol implementation. An unprivileged user can exploit a Use-After-Free UAF vulnerability, where the system attempts to use memory after it has been freed. This can lead to memory corruption,...
