kernel: vsock/virtio: bind uarg before filling zerocopy skb

A flaw was found in the Linux kernel's vsock/virtio transport. This vulnerability occurs when the system processes zerocopy socket buffers skbs and encounters an error during memory allocation for fixed-buffer vectored data. The system may attempt to free memory incorrectly, leading to a...

kernel: nfsd: initialize copy-notify stateid before publishing it

A flaw was found in the nfsd component of the Linux kernel. A use-after-free vulnerability exists due to improper initialization of the copy-notify state ID before its publication. A remote attacker could exploit this by sending a crafted OFFLOADCANCEL operation, leading to a race condition that...

kernel: idpf: fix read_dev_clk_lock spinlock init in idpf_ptp_init()

A flaw was found in the Linux kernel's Intel Ethernet controller driver idpf. This vulnerability occurs because a critical synchronization mechanism, known as a spinlock, is accessed before it has been properly initialized. An attacker could potentially exploit this timing issue to cause the syst...

kernel: vsock/vmci: fix UAF when peer resets connection during handshake

A flaw was found in the vsock/vmci component of the Linux kernel. A remote attacker could exploit a Use-After-Free UAF vulnerability when a peer resets a connection during the handshake process. This occurs because the system incorrectly handles reset packets, leading to a pending socket being le...

kernel: SUNRPC: pin upper rpc_clnt across the TLS connect_worker

A flaw was found in the Linux kernel's SUN Remote Procedure Call SUNRPC implementation. A use-after-free vulnerability exists in the Transport Layer Security TLS connection path. When a TLS handshake fails, the client resource can be prematurely freed, leading to a subsequent attempt to access th...

kernel: igc: set tx buffer type for SMD frames

A flaw was found in the Linux kernel's igc network driver. The igcfpeinitsmdframe function, responsible for initializing transmit TX buffer fields for Stream-based Data SMD frames, does not correctly set the buffer type. This can result in stale XDP eXpress Data Path or XSK AFXDP socket types...

kernel: SUNRPC: pin upper rpc_clnt across the TLS connect_worker

A flaw was found in the Linux kernel's SUN Remote Procedure Call SUNRPC implementation. A use-after-free vulnerability exists in the Transport Layer Security TLS connection path. When a TLS handshake fails, the client resource can be prematurely freed, leading to a subsequent attempt to access th...

kernel: NFSD: Fix SECINFO_NO_NAME decode error cleanup

A flaw was found in the Linux kernel's Network File System Daemon NFSD. The nfsd4decodesecinfononame function does not properly initialize a pointer sinexp before processing an incoming data stream. If the data stream is malformed or truncated, the uninitialized pointer can retain stale data from...

kernel: vsock/virtio: bind uarg before filling zerocopy skb

A flaw was found in the Linux kernel's vsock/virtio transport. This vulnerability occurs when the system processes zerocopy socket buffers skbs and encounters an error during memory allocation for fixed-buffer vectored data. The system may attempt to free memory incorrectly, leading to a...

kernel: vsock/virtio: fix zerocopy completion for multi-skb sends

A flaw was found in the Linux kernel's vsock/virtio component. This vulnerability occurs during zerocopy completion for large messages fragmented into multiple socket kernel buffers skbs. An issue in how user arguments uargs are handled for these buffers can lead to pinned user pages not being...

kernel: KVM: SEV: Require in-GHCB scratch area if GHCB v2+ is in use

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem, specifically within the SEV Secure Encrypted Virtualization feature. A malicious guest operating system utilizing SEV-SNP Secure Nested Paging can exploit an out-of-bounds write vulnerability due to improper...

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: nfsd: defer vfree of compound ops to fix rpc_status UAF

A flaw was found in the nfsd component of the Linux kernel. This vulnerability, a use-after-free, occurs when a specific memory buffer is prematurely released while another process is still trying to access it. This timing issue can lead to memory corruption. This could result in a system crash...

kernel: nfsd: fix stale s2s_cp_stateids IDR entry for async COPY

A flaw was found in the Linux kernel's Network File System Daemon nfsd component. When performing an asynchronous async copy operation, a programming error causes a stale identifier IDR entry to point to memory that has already been reused. This can lead to memory corruption, where the system...

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: udp: fix potential use-after-free in tunnel segmentation

A flaw was found in the Linux kernel's UDP User Datagram Protocol tunnel segmentation. This vulnerability arises when the system attempts to process network packets, specifically in the skbudptunnelsegment function. An attacker could potentially exploit a use-after-free condition, where the syste...

CVE-2026-98182

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local user with network administration privileges can cause a Denial of Service DoS by configuring an inactive network interface to active monitor mode and then bringing the interface up. Because the required transmit queue is...

CVE-2026-98179

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. This issue can lead to a Denial of Service DoS caused by resource exhaustion during device removal or driver unloading. Because the cleanup routine fails to release mapped input/output I/O register memory, a privileged local user could...

CVE-2026-98178

A flaw was found in the Linux kernel's AMD GPU driver. When compute subsystem initialization fails, uninitialized device structures remain attached to the graphics driver. A local user capable of triggering a GPU reset can cause the system to dereference an unallocated memory pointer, resulting i...

CVE-2026-98177

A flaw was found in the Linux kernel's AMD GPU driver amdkfd. A local user could trigger a Denial of Service DoS or system instability due to an integer underflow vulnerability during the calculation of the End of Pipe EOP ring buffer size. Under specific conditions, this improper calculation cou...
