kernel: keys: Pin request_key_auth payload in instantiate paths

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the handling of requestkeyauth payloads. This flaw occurs when the system attempts to use a key authorization payload after it has been released, which can lead to system instability or crashes. A local attacker could...

kernel: Bluetooth: HIDP: fix missing length checks in hidp_input_report()

A flaw was found in the Linux kernel's Bluetooth Human Interface Device Protocol HIDP. A remote attacker, by sending specially crafted truncated packets from a paired Bluetooth device, could trigger an out-of-bounds read in the hidpinputreport function. This vulnerability may lead to unintended...

kernel: Linux kernel Bluetooth RFCOMM: Denial of Service via use-after-free in set_termios

A flaw was found in the Linux kernel's Bluetooth RFCOMM subsystem. A race condition in the rfcommttysettermios function allows a session to be freed while it is still actively in use. This use-after-free UAF vulnerability can be exploited by a local attacker. Successful exploitation leads to a...

kernel: Bluetooth: L2CAP: Fix possible crash on l2cap_ecred_conn_rsp

A flaw was found in the Bluetooth L2CAP Logical Link Control and Adaptation Protocol component of the Linux kernel. When a device receives a connection response with an already-assigned destination Channel Identifier CID, the system may crash. This occurs because the kernel's procedure for...

kernel: Bluetooth: serialize accept_q access

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition exists in the handling of the acceptq within the btsockpoll function due to a lack of synchronization. This could allow a local attacker to cause a denial of service by manipulating socket operations during child teardow...

kernel: nvmet-tcp: check INIT_FAILED before nvmet_req_uninit in digest error path

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. When a data digest mismatch occurs, a reference count underflow can happen due to an unconditional cleanup call. This issue can lead to a use-after-free condition and ultimately result in a permanent workqueue deadlock...

kernel: Bluetooth: L2CAP: Fix potential user-after-free

A use-after-free flaw was identified in the Linux kernel’s Bluetooth L2CAP implementation. In certain conditions, when allocating a socket buffer via allocskb, the kernel may release and later reacquire the channel lock; if the channel is disconnected in the meantime, a subsequent reference to th...

kernel: RDMA/rxe: Reject unknown opcodes before ICRC processing

A flaw was found in the Linux kernel's Soft RoCE RDMA/rxe driver. An unauthenticated remote attacker can send a specially crafted UDP packet with an unknown opcode to trigger an out-of-bounds read. This vulnerability can lead to a kernel panic, effectively causing a Denial of Service DoS on the...

kernel: iommu/amd: Fix clone_alias() to use the original device's devid

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit AMD driver. The clonealias function incorrectly uses the device ID devid when handling alias devices. This can lead to the propagation of wrong or stale Device Table Entry DTE entries to alias devices, potentially...

kernel: net/mlx5: Fix MCIA register buffer overflow on 32 dword reads

A flaw was found in the net/mlx5 driver of the Linux kernel. When the driver attempts to read the MCIA register from a device advertising the mcia32dwords capability, the mlx5querymcia function can read more data than the allocated buffer can hold. This leads to a buffer overflow, which can cause...

kernel: iommu/vt-d: Clear Present bit before tearing down PASID entry

A flaw was found in the Linux kernel's Intel VT-d Virtualization Technology for Directed I/O Scalable Mode. When a Process Address Space ID PASID table entry is being removed, the system may attempt to clear the entry before properly signaling to the hardware that the entry is no longer active...

kernel: Bluetooth: SMP: force responder MITM requirements before building the pairing response

A flaw was found in the Linux kernel's Bluetooth Security Manager Protocol SMP. An attacker could exploit this vulnerability during the Bluetooth pairing process by manipulating authentication requirements. This could lead to the selection of a weaker pairing method than intended, potentially...

kernel: Bluetooth: btusb: revert use of devm_kzalloc in btusb

A use-after-free flaw was found in the Linux kernel's Bluetooth USB driver. The btusb driver binds to multiple USB interfaces INTF, ISOC, DIAG but allocates its data structure with devmkzalloc tied to a single interface. When that interface is released, the memory is freed while other interfaces...

kernel: Linux kernel Bluetooth: Denial of Service via race condition in hidp_session_thread

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition in the hidpsessionthread can lead to a use-after-free vulnerability. This occurs when a timer is active while its deletion function is called, causing memory to be accessed after it has been freed. A local attacker could...

kernel: crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg

A race condition was found in the Linux kernel cryptographic user API, AFALG in the way concurrent writes to the same AFALG socket are handled. Interleaved data and inconsistent internal socket state may result. A local user could use this flaw to crash the system or corrupt cryptographic operati...

kernel: dm cache policy smq: fix missing locks in invalidating cache blocks

A flaw was found in the Linux kernel's device-mapper dm cache policy, specifically within the smq module. In passthrough mode, the invalidatemapping operation lacks proper locking, allowing for concurrent access. This can lead to data races, resulting in data corruption or use-after-free issues,...

kernel: Bluetooth: RFCOMM: hold listener socket in rfcomm_connect_ind()

A flaw was found in the Linux kernel's Bluetooth RFCOMM Radio Frequency Communication subsystem. A race condition in the rfcommconnectind function, specifically during the handling of listener sockets, can lead to a use-after-free vulnerability. A local attacker could exploit this to cause a deni...

kernel: RDMA/rxe: Fix a use-after-free problem in rxe_mmap

A flaw was found in the Linux kernel's RDMA/rxe component. A race condition in the rxemmap function, which manages memory for Remote Direct Memory Access RDMA operations, can lead to a use-after-free vulnerability. A local attacker could exploit this timing issue to cause a system crash, resultin...

kernel: Bluetooth: RFCOMM: validate skb length in MCC handlers

A flaw was found in the Linux kernel's Bluetooth RFCOMM Radio Frequency Communication subsystem.
