Denial Of Service

The Tegra210-QSPI driver in the Linux kernel is vulnerable to a race condition where an unprotected NULL pointer check in the interrupt handler can be exploited by a local attacker with low privileges to cause a denial of service through kernel panic. The vulnerability occurs when the timeout path clears the curr_xfer pointer while the ISR thread is simultaneously accessing it, resulting in a NULL dereference. A patch is available to resolve this issue by properly synchronizing access with spinlock protection.

In the Linux kernel, the following vulnerability has been resolved: KVM: Don't clobber irqfd routing type when deassigning irqfd When deassigning a KVM_IRQFD, don't clobber the irqfd's copy of the IRQ's routing entry as doing so breaks kvm_arch_irq_bypass_del_producer() on x86 and arm64, which explicitly look for KVM_IRQ_ROUTING_MSI.

In the Linux kernel, the following vulnerability has been resolved: i2c: imx: preserve error state in block data length handler When a block read returns an invalid length, zero or >I2C_SMBUS_BLOCK_MAX, the length handler sets the state to IMX_I2C_STATE_FAILED.

A null pointer dereference in the CephFS kernel client's MDS authentication matching function (ceph_mds_auth_match()) allows local attackers with low privileges to cause a denial of service by crashing the kernel when the mds_namespace mount option is not specified. This regression affects Linux kernel versions 6.18-rc1 and later, impacting systems using CephFS with default mount configurations. No patch is currently available for this vulnerability.

In the Linux kernel, the following vulnerability has been resolved: net: cpsw: Execute ndo_set_rx_mode callback in a work queue Commit 1767bb2d47b7 ("ipv6: mcast: Don't hold RTNL for IPV6_ADD_MEMBERSHIP and MCAST_JOIN_GROUP.") removed the RTNL lock for IPV6_ADD_MEMBERSHIP and MCAST_JOIN_GROUP operations.

A null pointer dereference in the Linux kernel's mlx5e TC steering driver allows local attackers with user privileges to cause a denial of service by triggering improper flow deletion logic that attempts to access non-existent device peers. The vulnerability occurs when deleting TC flows without validating peer existence, leading to kernel crashes. No patch is currently available for this medium-severity flaw affecting Linux systems with Mellanox network drivers.

The Linux kernel bonding driver contains a use-after-free vulnerability in the slave device initialization path that allows local attackers with user privileges to cause memory corruption or denial of service. The flaw occurs when slave array updates happen before XDP setup completion, enabling the new slave to be used for transmission before being freed by error cleanup handlers. This affects Debian, Ubuntu, and other Linux distributions running vulnerable kernel versions.

A race condition in the Linux kernel's MPTCP address management function allows local attackers with user-level privileges to cause a denial of service through kernel crashes via improper list manipulation without RCU synchronization. The vulnerability exists in mptcp_pm_nl_flush_addrs_doit() where list_splice_init() is called while holding a spinlock, creating unsafe concurrent access conditions. Currently, no patch is available for this medium-severity vulnerability.

A NULL pointer dereference in the Intel ice network driver's ice_vsi_set_napi_queues() function can cause a kernel crash on Linux systems during suspend/resume operations when ring queue vectors are improperly initialized.

No patch is currently available for this vulnerability affecting Linux kernel v6.18 and the Intel E810 Ethernet adapter family.

The Linux kernel amdgpu graphics driver crashes with a NULL pointer dereference on APU platforms (Raven, Renoir) when SVM page fault recovery attempts to access uninitialized interrupt ring buffers that only exist on discrete GPUs. A local authenticated attacker can trigger this denial of service by enabling retry faults on affected APUs. No patch is currently available.

A null pointer dereference in the Linux kernel's perf scheduler functionality causes a denial of service when handling user space stacktraces for certain kernel tasks. Local attackers with low privileges can trigger this crash by exploiting inconsistent task classification logic that fails to properly identify user versus kernel tasks. The vulnerability affects the Linux kernel with no patch currently available.

A null pointer dereference in the Linux kernel's gs_usb driver can cause a denial of service when processing malformed USB bulk transfer callbacks, affecting systems with vulnerable CAN interface hardware. Local attackers with unprivileged access can trigger this crash by submitting crafted USB requests that fail resubmission. No patch is currently available for this vulnerability.

A race condition in the Linux kernel's NVMe target bio completion handler can cause a NULL pointer dereference when a bio is re-submitted while simultaneously being deinitialized, leading to denial of service on systems running affected kernel versions. Local attackers with access to NVMe target functionality can trigger this race to crash the kernel. A patch is not currently available.

A race condition in the Linux kernel's Bluetooth HCI UART driver allows local attackers with user privileges to trigger a null pointer dereference and cause a denial of service by initiating a TTY write wakeup during driver initialization. The vulnerability occurs when hci_uart_tx_wakeup() schedules write work before the protocol handler's private data structure is initialized, leading to a crash in hci_uart_write_work(). No patch is currently available for this issue.

The Linux kernel netdevsim driver contains a race condition in the bpf_bound_progs list operations where concurrent calls to nsim_bpf_create_prog() and nsim_bpf_destroy_prog() can corrupt the list and trigger kernel crashes. A local attacker with limited privileges can exploit this vulnerability to cause a denial of service by manipulating eBPF program creation and destruction. No patch is currently available for this issue.

A null pointer dereference in the Linux kernel's SCTP authentication initialization can be triggered by local attackers with user privileges to cause a denial of service through a crash in the packet transmission path. The vulnerability occurs when SCTP-AUTH key setup fails during association peer initialization, leaving a dangling pointer that is subsequently dereferenced. No patch is currently available for this medium-severity issue affecting the Linux kernel.

A NULL pointer dereference in the Linux kernel's ice driver occurs when devlink reload fails and the driver is subsequently removed, affecting systems using Intel ice network adapters. A local privileged user can trigger this denial of service condition by initiating a devlink reinit operation that fails, leaving the hardware in an uninitialized state. The vulnerability stems from a missing ice_deinit_hw() call in the devlink reinit path that leaves control queues uninitialized.

A race condition in the Linux kernel's serial driver allows local attackers with low privileges to bypass TTY device linkage during console configuration, potentially enabling unauthorized access to serial console interfaces on Qualcomm SoCs and other affected systems. The vulnerability stems from improper initialization ordering that fails to configure tty->port before uart_configure_port() is called, creating a window where user-space applications can open the console without proper driver linkage. No patch is currently available.
