In the Linux kernel, the following vulnerability has been resolved: usb: core: hcd: fix possible deadlock in rh control transfers >From within the SCSI error handler memory allocations must not trigger IO. Handling errors in UAS and the storage driver may involve resetting a device. The thread doing the reset itself relies on VM magic. However, that is insufficient, as resetting a device involves resuming it. Resumption as …
In the Linux kernel, the following vulnerability has been resolved: usbip: vhci_hcd: fix NULL deref in status_show_vhci platform_get_drvdata() can return NULL if a VHCI host controller's probe failed (e.g. due to USB bus number exhaustion). status_show_vhci() checked for a NULL pdev but not for a NULL hcd returned by platform_get_drvdata(). Passing NULL to hcd_to_vhci_hcd() does not return NULL - it returns a pointer offset…
In the Linux kernel, the following vulnerability has been resolved: RDMA/counter: Fix num_counters leak on bind_qp failure in alloc_and_bind() When __rdma_counter_bind_qp() fails in alloc_and_bind(), the error path jumps to err_mode which frees the counter without decrementing port_counter->num_counters. The only place that decrements is rdma_counter_free(), which is unreachable since the counter was never successfully boun…
In the Linux kernel, the following vulnerability has been resolved: virt: acrn: Fix irqfd use-after-free during eventfd shutdown acrn_irqfd_deassign() and the eventfd EPOLLHUP wakeup can race and free the same struct hsm_irqfd: CPU0 CPU1 ---- ---- eventfd_release() wake_up_poll(EPOLLHUP) hsm_irqfd_wakeup() queue_work(&irqfd->shutdown) …
In the Linux kernel, the following vulnerability has been resolved: tty: serial: 8250: protect against NULL uart->port.dev in register serial8250_register_8250_port() conditionally copies uart->port.dev from up->port.dev only when up->port.dev is non-NULL: if (up->port.dev) { uart->port.dev = up->port.dev; ... } So if both the existing uart slot and up have a NULL ->dev, uart->port.dev remains NULL. The very next AC…
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: goku_udc: avoid NULL deref of dev->driver in INT_USBRESET log goku_irq() handles a number of bus events under a single ep0 path. It already guards the gadget driver suspend/resume callbacks against a NULL ->driver: if (dev->gadget.speed != USB_SPEED_UNKNOWN && dev->driver && dev->driver->resume) { spin_unlock(&dev->lock); dev->drive…
In the Linux kernel, the following vulnerability has been resolved: driver core: Avoid warning when removing a device while its supplier is unbinding During driver removal, the following warning can appear: WARNING: CPU: 1 PID: 139 at drivers/base/core.c:1497 __device_links_no_driver+0xcc/0xfc ... Call trace: __device_links_no_driver+0xcc/0xfc (P) device_links_driver_cleanup+0xa8/0xf0 device_release_…
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Fix condition check in acpi_ps_parse_loop() Fix condition check for AML_ELSE_OP in acpi_ps_parse_loop() to prevent out-of-bounds access.
In the Linux kernel, the following vulnerability has been resolved: powercap: intel_rapl: Fix memory leak in rapl_add_package_cpuslocked() When topology_physical_package_id()/topology_logical_die_id() returns a negative value, rapl_add_package_cpuslocked() returns ERR_PTR(-EINVAL) directly without freeing the rapl_package structure that was just allocated by kzalloc_obj(), leaking memory on every failed package addition. U…
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: purge async notifications upon nic error This fixes a kernel panic in reconfig failure: 1. we have a BSS connection 2. we have a NAN connection 3. FW error occurs 4. reconfig restores the BSS connection 5. however, restoring the NAN connection fails due to a FW error. 6. erroneously, ieee80211_handle_reconfig_failure is called and marks…
In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/tegra/soctherma: Switch to devm cooling device registration Use devm_thermal_of_cooling_device_register() to simplify resource management and avoid manual cleanup in error paths. As a side effect this change has the benefit of solving an existing issue. Before, the function tegra_soctherm_remove() only called debugfs_remove_recursive() and …
In the Linux kernel, the following vulnerability has been resolved: rds: filter RDS_INFO_* getsockopt by caller's netns The RDS_INFO_* family of getsockopt(2) options reads several file-scope global lists that are not per-netns: rds_sock_info / rds6_sock_info, rds_sock_inc_info / rds6_sock_inc_info -> rds_sock_list rds_tcp_tc_info / rds6_tcp_tc_info -> rds_tcp_tc_list rds_conn_info / rds6_conn_inf…
In the Linux kernel, the following vulnerability has been resolved: ipv6: addrconf: fix temp address generation after prefix deprecation When a router temporarily deprecates an IPv6 prefix (either by sending a Router Advertisement with Preferred Lifetime = 0 or by letting the lifetime expire) and later restores it, the kernel permanently loses its ability to generate temporary privacy addresses (RFC 8981) for that prefix. …
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Add validation for node in acpi_ns_build_normalized_path() Add validation for node in acpi_ns_build_normalized_path() to prevent use-after-free vulnerabilities.
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Add package limit checks in parser functions Add package limit checks in parser functions to prevent out-of-bounds access.
In the Linux kernel, the following vulnerability has been resolved: ACPICA: validate handler object type in two places ACPICA: validate handler object type in acpi_ev_has_default_handler() and acpi_ev_find_region_handler().
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Fix integer overflow in acpi_ex_opcode_3A_1T_1R() (mid_op) Add overflow check for Index + Length to prevent integer overflow when calculating the truncation length.

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: fix node refcount leak on ctrl packet alloc failure qrtr_send_resume_tx() calls qrtr_node_lookup() which takes a reference on the returned node. If the subsequent call to qrtr_alloc_ctrl_packet() fails due to memory allocation failure, the function returns -ENOMEM without calling qrtr_node_release() to release the node reference. Add qrtr_node_r…
