| CVE-2026-97991 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: vdpa_sim_blk: reject out-of-range sector starts vdpasim_blk_check_range() logs an invalid start sector but continues validating the request. The subsequent unsigned capacity subtraction can underflow and let an out-of-range buffer offset reach the data path. The invalid offset is used by three request paths. VIRTIO_BLK_T_OUT copies guest data to blk->buffer + offset through vringh_iov_pull_iotlb(), causing an out-of-bounds write in _copy_from_iter() or memcpy(). VIRTIO_BLK_T_IN copies from blk->buffer + offset to the guest through vringh_iov_push_iotlb(), causing an out-of-bounds read in _copy_to_iter(). VIRTIO_BLK_T_WRITE_ZEROES passes blk->buffer + offset to memset(), causing an out-of-bounds write. Reject starts at or beyond the capacity before the subtraction. Treat the capacity boundary as invalid because the IN and OUT paths round byte counts down to sectors for validation but later copy the original byte counts. A sub-sector request at the capacity boundary would otherwise still access past the end of the buffer. I found this bug myself, though the patch was written with AI assistance. | ||||
| CVE-2026-97990 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: vdpa_sim_net: check TX pull result before RX copy vringh_iov_pull_iotlb() returns a signed byte count. A failed TX pull is currently added to the unsigned byte counter and then passed as a size_t length to receive_filter() and vringh_iov_push_iotlb(). A negative error can therefore become a large length in the RX path. Handle non-positive pull results before every length use. Count the TX error and complete the consumed TX descriptor with zero bytes. I found this bug myself, though the patch was written with AI assistance. | ||||
| CVE-2026-97903 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: exit: hold a reference to thread_pid across proc_flush_pid Commit 0a36bad01731 ("release_task: kill the no longer needed get/put_pid(thread_pid)") removed the reference around proc_flush_pid(). It assumed that free_pids(post.pids) at the end of release_task() would keep thread_pid alive until then. That assumption is wrong. __change_pid() only records a detached PID in post.pids when pid_has_task() is false for every PIDTYPE. If another task still uses the exiting task's PID as its process group or session ID, __unhash_process() removes the exiting task's PIDTYPE_PID link but leaves the PID out of post.pids. release_task() therefore holds no reference to it after dropping tasklist_lock. The other task can then remove the remaining PIDTYPE links. Its free_pids() call schedules delayed_put_pid(), and the RCU callback can free the PID before the first release_task() reaches proc_flush_pid(). An unprivileged reproducer races wait4(-1) against setsid() to trigger this ordering. Three of three fresh v7.2 KASAN boots reported: BUG: KASAN: slab-use-after-free in proc_invalidate_siblings_dcache+0x3e2/0x3f0 Read of size 8 by task h7_pid_reaper/1921 Call Trace: proc_invalidate_siblings_dcache release_task wait_consider_task __do_wait do_wait kernel_wait4 Freed by task 0: kmem_cache_free put_pid delayed_put_pid rcu_core Last potentially related work creation: __call_rcu_common free_pids ksys_setsid KASAN identified a 144-byte object from the pid cache and located the bad read 80 bytes into the freed object, matching pid->inodes. With an explicit reference, three of three fresh boots completed without a KASAN report. The concurrent RCU callback dropped its reference while proc_flush_pid() was protected, and the balancing put_pid() performed the final free afterward. Take a reference before __unhash_process() clears p->thread_pid and release it after proc_flush_pid() completes. A tested source reproducer is available privately on request. No controlled read or write, information leak, or privilege escalation is claimed. The mainline patch applies directly to v6.19.y and newer; v6.16.y through v6.18.y need a context-adjusted backport. | ||||
| CVE-2026-18710 | 1 Mongodb | 2 Java Driver, Mongodb Server | 2026-09-25 | 6.5 Medium |
| A MongoDB driver component could write sensitive configuration information, including a credential used for outbound network connectivity, to application log output in cleartext during routine client initialization. This occurs automatically as part of normal operation and requires no special privileges to trigger. A party able to read the affected application's logs or downstream log-aggregation storage could recover the credential and reuse it to authenticate to the associated network infrastructure. This issue affects confidentiality only. | ||||

| CVE-2026-97904 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cpufreq: initialize policy rwsem before sysfs publication cpufreq_policy_alloc() initializes policy->rwsem after kobject_init_and_add() has created the policy sysfs directory and its default attributes. A sysfs access can therefore reach a policy callback before the semaphore has been initialized. Initialize policy->rwsem before publishing the policy kobject so sysfs callbacks always see an initialized semaphore. | ||||
| CVE-2026-97905 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cpufreq: zero-initialize policy cpumask before sysfs publication cpufreq_policy_alloc() allocates policy->cpus with alloc_cpumask_var(), i.e. without __GFP_ZERO, unlike the sibling related_cpus and real_cpus masks. With CONFIG_CPUMASK_OFFSTACK=y the mask is a separate kmalloc_node() allocation, so its bitmap holds whatever the slab allocator left behind: cpufreq_online() cpufreq_policy_alloc() alloc_cpumask_var(&policy->cpus) /* bitmap is uninitialized */ kobject_init_and_add() /* policy%u/ appears in sysfs */ cpufreq_policy_online() cpumask_copy(policy->cpus, cpumask_of(cpu)) /* first valid value */ This leaves a window in which the sysfs attributes are already reachable while policy->cpus is still garbage. show()/store() gate on policy_is_inactive(), i.e. cpumask_empty(policy->cpus), so a non-zero bitmap makes them run the attribute callbacks on a policy that is not initialized yet. Fix this by using zalloc_cpumask_var() for policy->cpus. | ||||
| CVE-2026-97907 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btrtl: Don't leak return code when parsing firmware format v2 When key_id from chip is zero, rtlbt_parse_firmware_v2() intentionally ignores all security headers. However, the implementation simply breaks from a switch statement and leaks uninitialized return code `rc' (if the first section is a security one) or the previous section's `rc'. Fix it by really skipping a loop with `continue'. For consistency and readability, also do the same for the default case. | ||||
| CVE-2026-97909 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: sti: initialize IRQ lock before requesting IRQ uni_reader_init() registers the shared IRQ before initializing reader->irq_lock. A pending interrupt can invoke the handler while the lock is still uninitialized. Initialize the lock before registering the IRQ so the interrupt path always sees valid lock state. | ||||
| CVE-2026-97914 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Fix ethosu_job_open() return value A WARN_ON() returns a 0 or 1, not the original negative errno. Just drop the WARN_ON() as the FD open will pass the return code to userspace and there's only one possible source of the error (drm_sched_entity_init()). | ||||
| CVE-2026-97923 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: tracing: Free histogram the var ref when its initialization fails create_var_ref() allocates a VAR_REF hist_field and then calls init_var_ref() to fill it in. When that fails the field is leaked. commit 656fe2ba85e8 ("tracing: Use hist trigger's var_ref array to destroy var_refs") made destroy_hist_field() return early for HIST_FIELD_FL_VAR_REF, since var refs are freed by walking the trigger's var_refs[] array instead. create_var_ref() adds the field to that array only after init_var_ref() has succeeded, so on this path the field is in neither place and nothing frees it. The call was correct when it was written, before var refs were taken out of destroy_hist_field(). init_var_ref() cannot free it either. The caller owns the field, so init_var_ref() undoes only its own string allocations and leaves the field alone. Freeing it there would leave create_var_ref() passing freed memory to destroy_hist_field(), which reads its flags. Call __destroy_hist_field(), which frees the field without consulting the flag. | ||||
| CVE-2026-97924 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: tracing/user_events: Don't destroy fields when event removal fails destroy_user_event() destroys the event's fields before attempting to remove the trace event call. If user_event_set_call_visible() fails, e.g. because the event is still enabled and trace_remove_event_call() returns -EBUSY, the event is left registered with an irreversibly destroyed field list. Any subsequent interaction with the event then operates on an empty field list while it is still fully visible in tracefs. Move the field destruction after the call removal, and splice the field list back onto the event when the removal fails so the event remains in a consistent state. | ||||
| CVE-2026-97983 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: vduse: return compat ioctl results directly The compat handler handles VDUSE_IOTLB_GET_FD and VDUSE_VQ_GET_INFO, but then calls the native handler. Their different command sizes make native dispatch return -ENOIOCTLCMD. For GET_FD, this overwrites receive_fd()'s return value after the descriptor is installed, leaking one fd per call. Return handled compat results directly and use native dispatch only for other commands. | ||||
