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: 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: 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 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/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: 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: 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...
