| CVE-2026-68364 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 5.0 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix ISM dc_lock deadlock during suspend [Why] System hang observed during suspend/resume while video is playing. amdgpu_dm_ism_disable() is called under dc_lock and waits for ISM delayed work via disable_delayed_work_sync(). The work handlers themselves take dc_lock, producing an ABBA deadlock when a worker is in flight at suspend time. [How] Split the disable path into two phases with opposite locking contracts: 1. amdgpu_dm_ism_disable() -- quiesces workers, must NOT hold dc_lock. 2. amdgpu_dm_ism_force_full_power() (new) -- drives the ISM FSM back to FULL_POWER_RUNNING, must hold dc_lock. | ||||

| CVE-2026-64250 | 1 Linux | 1 Linux Kernel | 2026-08-12 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: LoongArch: Report dying CPU to RCU in stop_this_cpu() This is a port of MIPS commit 9f3f3bdc6d9dac1 ("MIPS: smp: report dying CPU to RCU in stop_this_cpu()"). smp_send_stop() parks all secondary CPUs in stop_this_cpu(). And the function marks the CPU offline for the scheduler via set_cpu_online(false) but never informs RCU, so RCU keeps expecting a quiescent state from CPUs that are now spinning forever with interrupts disabled. As long as nothing waits for an RCU grace period after smp_send_stop() this is harmless, which is why it went unnoticed. However, since commit 91840be8f710370 ("irq_work: Fix use-after-free in irq_work_single() on PREEMPT_RT"), irq_work_sync() calls synchronize_rcu() on architectures without an irq_work self-IPI, i.e. where arch_irq_work_has_interrupt() returns false. Any irq_work_sync() issued in the reboot/shutdown/halt path after smp_send_stop() then blocks on a grace period that can never complete, hanging the reboot: WARNING: CPU: 0 PID: 15 at kernel/irq_work.c:144 irq_work_queue_on ... rcu: INFO: rcu_sched detected stalls on CPUs/tasks: rcu: Offline CPU 1 blocking current GP. rcu: Offline CPU 2 blocking current GP. rcu: Offline CPU 3 blocking current GP. This issue needs some hacks to reproduce, and it was not noticed on LoongArch because arch_irq_work_has_interrupt() usually returns true. Call rcutree_report_cpu_dead() once interrupts are disabled, mirroring the generic CPU-hotplug offline path, so RCU stops waiting on the parked CPUs and grace periods can still complete. LoongArch shuts down all CPUs here without going through the CPU-hotplug mechanism, so this report is not otherwise issued. | ||||
| CVE-2026-14258 | 2 Dhcpcd Project, Redhat | 2 Dhcpcd, Enterprise Linux | 2026-08-12 | 6.5 Medium |
| A flaw was found in dhcpcd's IPv6 Neighbor Discovery Router Advertisement processing. A specially crafted IPv6 Router Advertisement containing a zero-length Neighbor Discovery option can bypass validation during packet storage and later be reparsed without adequate validation, causing the parser to enter a non-advancing loop. Successful exploitation may result in excessive CPU consumption, leading to a denial of service. | ||||
| CVE-2026-10683 | 1 Zephyrproject | 1 Zephyr | 2026-08-12 | 2.4 Low |
| In the Synopsys DesignWare I2C driver (drivers/i2c/i2c_dw.c) operating in target/slave mode, the rx_full interrupt handler gates the write_requested() callback on dw->state != CMD_SEND, and dw->state is only reset to READY on a STOP interrupt. The START_DET interrupt, whose handler in i2c_dw_slave_read_clear_intr_bits() would reset the state on every (re)START, was never added to the enabled interrupt mask in i2c_dw_slave_register(), so that recovery path was dead code. As a result, if the STOP interrupt is lost (bus glitch/reset, or a concurrent master driving STOP) or the bus master issues a legal WRITE-repeated-START-WRITE sequence with the same direction, the driver remains in CMD_SEND permanently and never invokes write_requested() again for the life of the target. An I2C master on the same physical bus can deliberately trigger this, causing the I2C target function to malfunction for all subsequent write transactions and desynchronizing consumer framing state (e.g. MCTP-over-I2C), a recoverable-by-reset denial of service of the target peripheral. The fix unmasks START_DET so the state is reset at every bus (re)START. Impact is availability-only over a local board-level bus; no memory corruption results in the in-tree consumer, whose per-byte buffer write is independently bounds-checked. | ||||

| CVE-2024-20353 | 1 Cisco | 4 Adaptive Security Appliance Software, Asa, Firepower Threat Defense Software and 1 more | 2026-08-11 | 8.6 High |
| A vulnerability in the management and VPN web servers for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to incomplete error checking when parsing an HTTP header. An attacker could exploit this vulnerability by sending a crafted HTTP request to a targeted web server on a device. A successful exploit could allow the attacker to cause a DoS condition when the device reloads. | ||||
| CVE-2023-20083 | 1 Cisco | 1 Secure Firewall Threat Defense | 2026-08-11 | 8.6 High |
| A vulnerability in ICMPv6 inspection when configured with the Snort 2 detection engine for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the CPU of an affected device to spike to 100 percent, which could stop all traffic processing and result in a denial of service (DoS) condition. FTD management traffic is not affected by this vulnerability. This vulnerability is due to improper error checking when parsing fields within the ICMPv6 header. An attacker could exploit this vulnerability by sending a crafted ICMPv6 packet through an affected device. A successful exploit could allow the attacker to cause the device to exhaust CPU resources and stop processing traffic, resulting in a DoS condition. Note: To recover from the DoS condition, the Snort 2 Detection Engine or the Cisco FTD device may need to be restarted. | ||||

| CVE-2026-68408 | 1 Linux | 1 Linux Kernel | 2026-08-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: convert pmsr_free_wk to wiphy_work to fix deadlock When a netlink socket that owns a PMSR session is closed, cfg80211_release_pmsr() clears the request's nl_portid and queues pmsr_free_wk to call cfg80211_pmsr_process_abort() asynchronously. If the interface tears down concurrently, cfg80211_pmsr_wdev_down() is called under wiphy_lock and calls cancel_work_sync(&pmsr_free_wk) to wait for any running work. The work function acquires wiphy_lock via guard(wiphy) before calling process_abort. This is a deadlock: wdev_down holds wiphy_lock and blocks inside cancel_work_sync(); pmsr_free_wk blocks trying to acquire that same wiphy_lock. Neither thread can proceed. The same deadlock is reachable from cfg80211_leave_locked(), which calls cfg80211_pmsr_wdev_down() for all interface types under wiphy_lock. Fix this by converting pmsr_free_wk from a plain work_struct to a wiphy_work. The wiphy_work dispatcher holds wiphy_lock when running work items, so the explicit guard(wiphy) in the work function is no longer needed. wiphy_work_cancel() can be called safely while holding wiphy_lock - since wiphy_lock prevents the work from running concurrently, wiphy_work_cancel() never blocks, eliminating the deadlock. Remove the cancel_work_sync() for pmsr_free_wk from the NETDEV_GOING_DOWN handler. cfg80211_leave(), called unconditionally just before it, already cancels any pending work under wiphy_lock via wiphy_work_cancel() inside cfg80211_pmsr_wdev_down(). | ||||
| CVE-2026-68319 | 1 Linux | 1 Linux Kernel | 2026-08-10 | 4.1 Medium |
| In the Linux kernel, the following vulnerability has been resolved: pds_core: fix deadlock between reset thread and remove pci_reset_function() acquires device_lock before performing the reset. pdsc_remove() is called by the PCI core with device_lock already held. If pdsc_pci_reset_thread() is running when pdsc_remove() is called, destroy_workqueue() will block waiting for the work to complete, while the work is blocked waiting for device_lock - deadlock. Use pci_try_reset_function() which uses pci_dev_trylock() internally. This acquires both the device lock and the PCI config access lock without blocking - if either lock is contended, it returns -EAGAIN immediately. This avoids the deadlock while also ensuring proper config space access serialization during the reset. The pci_dev_get/put calls are also removed as they were unnecessary - the driver-owned workqueue is destroyed in pdsc_remove(), guaranteeing the work completes before remove returns. The PCI core holds its reference to pci_dev throughout the entire unbind sequence. | ||||

| CVE-2026-8798 | 1 Legion Of The Bouncy Castle Inc. | 1 Bc-fja | 2026-08-10 | N/A |
| In Bouncy Castle for Java FIPS (BC-FJA) before bc-fips 2.1.3, the native entropy source used on Intel platforms retried the CPU entropy instructions without any bound. RDSEED and RDRAND report failure through their carry flag, and the JNI seeding routine spun re-issuing the instruction for as long as that flag stayed clear, so a persistent failure of the on-chip entropy source - whether from a hardware fault, from the underlying DRBG being exhausted by contention across many cores, or from a hypervisor that does not provide the instruction - left the calling thread looping indefinitely inside the JNI call, where it could be neither interrupted nor timed out. Any operation drawing from the native entropy source could therefore hang, denying service to the application. The retry loops are now bounded (200 attempts for RDSEED and 20 for RDRAND, twice the baselines given in Intel's Digital Random Number Generator software implementation guide), pausing between attempts and, on exhaustion, clearing any partially written buffer and throwing rather than continuing to spin. The clear is performed by an un-elidable memzero, which uses a volatile pointer and an assembly memory barrier so that a compiler cannot optimise the erase away as a dead store. Bouncy Castle for Java (bcprov) is not affected, as it has no native entropy source; the 1.0.X and 2.0.X FIPS series are not affected. | ||||

This issue is fixed in 3.6.25 and 3.7.10. | ||||
