| In the Linux kernel, the following vulnerability has been resolved: dm thin: Fix UAF in run_timer_softirq() When dm_resume() and dm_destroy() are concurrent, it will lead to UAF, as follows: BUG: KASAN: use-after-free in __run_timers+0x173/0x710 Write of size 8 at addr ffff88816d9490f0 by task swapper/0/0 <snip> Call Trace: <IRQ> dump_stack_lvl+0x73/0x9f print_report.cold+0x132/0xaa2 _raw_spin_lock_irqsave+0xcd/0x160 __run_timers+0x173/0x710 kasan_report+0xad/0x110 __run_timers+0x173/0x710 __asan_store8+0x9c/0x140 __run_timers+0x173/0x710 call_timer_fn+0x310/0x310 pvclock_clocksource_read+0xfa/0x250 kvm_clock_read+0x2c/0x70 kvm_clock_get_cycles+0xd/0x20 ktime_get+0x5c/0x110 lapic_next_event+0x38/0x50 clockevents_program_event+0xf1/0x1e0 run_timer_softirq+0x49/0x90 __do_softirq+0x16e/0x62c __irq_exit_rcu+0x1fa/0x270 irq_exit_rcu+0x12/0x20 sysvec_apic_timer_interrupt+0x8e/0xc0 One of the concurrency UAF can be shown as below: use free do_resume | __find_device_hash_cell | dm_get | atomic_inc(&md->holders) | | dm_destroy | __dm_destroy | if (!dm_suspended_md(md)) | atomic_read(&md->holders) | msleep(1) dm_resume | __dm_resume | dm_table_resume_targets | pool_resume | do_waker #add delay work | dm_put | atomic_dec(&md->holders) | | dm_table_destroy | pool_dtr | __pool_dec | __pool_destroy | destroy_workqueue | kfree(pool) # free pool time out __do_softirq run_timer_softirq # pool has already been freed This can be easily reproduced using: 1. create thin-pool 2. dmsetup suspend pool 3. dmsetup resume pool 4. dmsetup remove_all # Concurrent with 3 The root cause of this UAF bug is that dm_resume() adds timer after dm_destroy() skips cancelling the timer because of suspend status. After timeout, it will call run_timer_softirq(), however pool has already been freed. The concurrency UAF bug will happen. Therefore, cancelling timer again in __pool_destroy(). | ||||

| In the Linux kernel, the following vulnerability has been resolved: tpm: acpi: Call acpi_put_table() to fix memory leak The start and length of the event log area are obtained from TPM2 or TCPA table, so we call acpi_get_table() to get the ACPI information, but the acpi_get_table() should be coupled with acpi_put_table() to release the ACPI memory, add the acpi_put_table() properly to fix the memory leak. While we are at it, remove the redundant empty line at the end of the tpm_read_log_acpi(). | ||||

| CVE-2022-50558 | 1 Linux | 1 Linux Kernel | 2026-05-11 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: regmap-irq: Use the new num_config_regs property in regmap_add_irq_chip_fwnode Commit faa87ce9196d ("regmap-irq: Introduce config registers for irq types") added the num_config_regs, then commit 9edd4f5aee84 ("regmap-irq: Deprecate type registers and virtual registers") suggested to replace num_type_reg with it. However, regmap_add_irq_chip_fwnode wasn't modified to use the new property. Later on, commit 255a03bb1bb3 ("ASoC: wcd9335: Convert irq chip to config regs") removed the old num_type_reg property from the WCD9335 driver's struct regmap_irq_chip, causing a null pointer dereference in regmap_irq_set_type when it tried to index d->type_buf as it was never allocated in regmap_add_irq_chip_fwnode: [ 39.199374] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 [ 39.200006] Call trace: [ 39.200014] regmap_irq_set_type+0x84/0x1c0 [ 39.200026] __irq_set_trigger+0x60/0x1c0 [ 39.200040] __setup_irq+0x2f4/0x78c [ 39.200051] request_threaded_irq+0xe8/0x1a0 Use num_config_regs in regmap_add_irq_chip_fwnode instead of num_type_reg, and fall back to it if num_config_regs isn't defined to maintain backward compatibility. | ||||

| In the Linux kernel, the following vulnerability has been resolved: pinctrl: thunderbay: fix possible memory leak in thunderbay_build_functions() The thunderbay_add_functions() will free memory of thunderbay_funcs when everything is ok, but thunderbay_funcs will not be freed when thunderbay_add_functions() fails, then there will be a memory leak, so we need to add kfree() when thunderbay_add_functions() fails to fix it. In addition, doing some cleaner works, moving kfree(funcs) from thunderbay_add_functions() to thunderbay_build_functions(). | ||||

| CVE-2022-50381 | 1 Linux | 1 Linux Kernel | 2026-05-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: md: fix a crash in mempool_free There's a crash in mempool_free when running the lvm test shell/lvchange-rebuild-raid.sh. The reason for the crash is this: * super_written calls atomic_dec_and_test(&mddev->pending_writes) and wake_up(&mddev->sb_wait). Then it calls rdev_dec_pending(rdev, mddev) and bio_put(bio). * so, the process that waited on sb_wait and that is woken up is racing with bio_put(bio). * if the process wins the race, it calls bioset_exit before bio_put(bio) is executed. * bio_put(bio) attempts to free a bio into a destroyed bio set - causing a crash in mempool_free. We fix this bug by moving bio_put before atomic_dec_and_test. We also move rdev_dec_pending before atomic_dec_and_test as suggested by Neil Brown. The function md_end_flush has a similar bug - we must call bio_put before we decrement the number of in-progress bios.

| In the Linux kernel, the following vulnerability has been resolved: tty: serial: fsl_lpuart: disable dma rx/tx use flags in lpuart_dma_shutdown lpuart_dma_shutdown tears down lpuart dma, but lpuart_flush_buffer can still occur which in turn tries to access dma apis if lpuart_dma_tx_use flag is true. At this point since dma is torn down, these dma apis can abort. Set lpuart_dma_tx_use and the corresponding rx flag lpuart_dma_rx_use to false in lpuart_dma_shutdown so that dmas are not accessed after they are relinquished. Otherwise, when try to kill btattach, kernel may panic. This patch may fix this issue. root@imx8ulpevk:~# btattach -B /dev/ttyLP2 -S 115200 ^C[ 90.182296] Internal error: synchronous external abort: 96000210 [#1] PREEMPT SMP [ 90.189806] Modules linked in: moal(O) mlan(O) [ 90.194258] CPU: 0 PID: 503 Comm: btattach Tainted: G O 5.15.32-06136-g34eecdf2f9e4 #37 [ 90.203554] Hardware name: NXP i.MX8ULP 9X9 EVK (DT) [ 90.208513] pstate: 600000c5 (nZCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 90.215470] pc : fsl_edma3_disable_request+0x8/0x60 [ 90.220358] lr : fsl_edma3_terminate_all+0x34/0x20c [ 90.225237] sp : ffff800013f0bac0 [ 90.228548] x29: ffff800013f0bac0 x28: 0000000000000001 x27: ffff000008404800 [ 90.235681] x26: ffff000008404960 x25: ffff000008404a08 x24: ffff000008404a00 [ 90.242813] x23: ffff000008404a60 x22: 0000000000000002 x21: 0000000000000000 [ 90.249946] x20: ffff800013f0baf8 x19: ffff00000559c800 x18: 0000000000000000 [ 90.257078] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000 [ 90.264211] x14: 0000000000000003 x13: 0000000000000000 x12: 0000000000000040 [ 90.271344] x11: ffff00000600c248 x10: ffff800013f0bb10 x9 : ffff000057bcb090 [ 90.278477] x8 : fffffc0000241a08 x7 : ffff00000534ee00 x6 : ffff000008404804 [ 90.285609] x5 : 0000000000000000 x4 : 0000000000000000 x3 : ffff0000055b3480 [ 90.292742] x2 : ffff8000135c0000 x1 : ffff00000534ee00 x0 : ffff00000559c800 [ 90.299876] Call trace: [ 90.302321] fsl_edma3_disable_request+0x8/0x60 [ 90.306851] lpuart_flush_buffer+0x40/0x160 [ 90.311037] uart_flush_buffer+0x88/0x120 [ 90.315050] tty_driver_flush_buffer+0x20/0x30 [ 90.319496] hci_uart_flush+0x44/0x90 [ 90.323162] +0x34/0x12c [ 90.327253] tty_ldisc_close+0x38/0x70 [ 90.331005] tty_ldisc_release+0xa8/0x190 [ 90.335018] tty_release_struct+0x24/0x8c [ 90.339022] tty_release+0x3ec/0x4c0 [ 90.342593] __fput+0x70/0x234 [ 90.345652] ____fput+0x14/0x20 [ 90.348790] task_work_run+0x84/0x17c [ 90.352455] do_exit+0x310/0x96c [ 90.355688] do_group_exit+0x3c/0xa0 [ 90.359259] __arm64_sys_exit_group+0x1c/0x20 [ 90.363609] invoke_syscall+0x48/0x114 [ 90.367362] el0_svc_common.constprop.0+0xd4/0xfc [ 90.372068] do_el0_svc+0x2c/0x94 [ 90.375379] el0_svc+0x28/0x80 [ 90.378438] el0t_64_sync_handler+0xa8/0x130 [ 90.382711] el0t_64_sync+0x1a0/0x1a4 [ 90.386376] Code: 17ffffda d503201f d503233f f9409802 (b9400041) [ 90.392467] ---[ end trace 2f60524b4a43f1f6 ]--- [ 90.397073] note: btattach[503] exited with preempt_count 1 [ 90.402636] Fixing recursive fault but reboot is needed! | ||||

The mutex is only meant to protect udc->driver along with a few other things. As far as I can tell, there's no reason for the mutex to be held while the gadget core calls a gadget driver's ->bind or ->unbind routine, or while a UDC is being started or stopped. (This accounts for link #1 in the chain above, where the mutex is held while the dwc2_hsotg_udc is started as part of driver probing.) Gadget drivers' ->disconnect callbacks are problematic. Even though usb_gadget_disconnect() will now acquire the udc_mutex, there's a window in usb_gadget_bind_driver() between the times when the mutex is released and the ->bind callback is invoked. If a disconnect occurred during that window, we could call the driver's ->disconnect routine before its ->bind routine. To prevent this from happening, it will be necessary to prevent a UDC from connecting while it has no gadget driver. This should be done already but it doesn't seem to be; currently usb_gadget_connect() has no check for this. Such a check will have to be added later. Some degree of mutual exclusion is required in soft_connect_store(), which can dereference udc->driver at arbitrary times since it is a sysfs callback. The solution here is to acquire the gadget's device lock rather than the udc_mutex. Since the driver core guarantees that the device lock is always held during driver binding and unbinding, this will make the accesses in soft_connect_store() mutually exclusive with any changes to udc->driver. Lastly, it turns out there is one place which should hold the udc_mutex but currently does not: The function_show() routine needs protection while it dereferences udc->driver. The missing lock and unlock calls are added. | ||||

| CVE-2026-42874 | 2026-05-11 | 3.7 Low | ||
| Microdot is a minimalistic Python web framework. Prior to 2.6.1, the Response.set_cookie() method does not sanitize its string arguments, and in particular will not detect the presence of the \r\n sequence in them. This can be a potential source of header injection attacks. For a header injection attack through this issue to be possible, an attacker must first infiltrate the client (for example through an independent XSS attack), so that it can send malicious information that is destined to be stored in a cookie by the server on behalf of the victim. An attacker that infiltrates one client can only orchestrate a header injection attack for that client, all other clients that were not infiltrated are safe. This vulnerability is fixed in 2.6.1. | ||||
