The Linux kernel vulnerability, CVE-2026-72095, involves a dma-fence issue that could potentially cause problems if not handled correctly. The dma_fence_dedup_array() function did not correctly handle 0-count input, but now returns 0 early for 0-count input, aligning with documentation and preventing potential problems. Linux kernel users and administrators should be aware of this vulnerability and ensure [truncated]
A potential NULL pointer dereference vulnerability was resolved in the Linux kernel's dma-buf and dma-fence components. The issue arose from a mechanism allowing fence producers to decouple from fence consumers, which could lead to a NULL pointer dereference if not handled properly. The solution involves using the ops pointer itself as the synchronization point to prevent out-of-order operations on weakly [truncated]
The Linux kernel has a use-after-free vulnerability in the amdxdna_gem_dmabuf_mmap() function. When vm_insert_pages() fails, the error path calls vma->vm_ops->close(vma), which releases the GEM object reference. However, the close_vma label then falls through to put_obj, causing a second release of the same object, leading to a use-after-free. The issue is resolved by returning directly from close_vma ins [truncated]
A vulnerability was found in the Linux kernel's accel/amdxdna component. The amdxdna_drm_sync_bo_ioctl() function incorrectly used the BO's stored client pointer instead of the ioctl caller's drm_file for SYNC_DIRECT_FROM_DEVICE. This mismatch caused issues with the handle namespace for debug_bo_hdl and the owner of the hardware context xarray. The fix involves passing filp->driver_priv instead of abo->cl [truncated]
A DMA mapping leak was found in the Linux kernel's hpsa driver on the IOACCEL2 reset path. If phys_disk->in_reset is set, the function returns directly without undoing the resources acquired for the command. The issue has been resolved by adding the missing error cleanup. This vulnerability affects Linux kernel developers and users who rely on the hpsa driver. The DMA mapping leak could potentially lead t [truncated]
The Linux kernel vulnerability (CVE-2026-72087) involves a memory leak in the lpfc_sli4_driver_resource_setup() function.

The Linux kernel has a vulnerability in the scsi: xen: scsiback module. When a task-management request submission fails, the command tag is not freed, potentially leading to a leak of command tags for a LUN's session. This issue can be triggered by a pvSCSI guest issuing VSCSIIF_ACT_SCSI_ABORT or RESET requests. The vulnerability has been resolved by freeing the command tag on the TMR submit-failure path. [truncated]
The Linux kernel has a vulnerability in the SCSI target subsystem. The `target_parse_pr_out_transport_id` function does not validate the length of the received buffer, leading to an out-of-bounds read when parsing an iSCSI TransportID. This can cause a kernel crash (KASAN: vmalloc-out-of-bounds in strstr). The vulnerability is reachable by any fabric that delivers a PR OUT to a device exported through an [truncated]
A use-after-free vulnerability was found in the Linux kernel's SCSI target core, specifically in the handling of iSCSI ISID during the REGISTER AND MOVE operation. The issue arises from the premature unmapping of the parameter list buffer, leading to a use-after-free read when the buffer is accessed after being unmapped. This vulnerability affects Linux kernel developers, Linux distribution maintainers, a [truncated]
A use-after-free vulnerability exists in the Linux kernel's fs/resctrl during unmount or failure teardown. The RDT_DELETED flag is not set for the default resource group, allowing a concurrent reader to access already-freed monitoring event file private data. This can occur when a user opens a file for reading and a concurrent operation frees the file private data and destroys the kernfs node without wait [truncated]
A use-after-free and double-free vulnerability was found in the ims-pcu disconnect function of the Linux kernel. The ims_pcu_disconnect function only intended to perform cleanup when the primary control interface is unbound. However, it currently relies on the interface class to distinguish between control and data interfaces. A malicious device could present a data interface with the same class as the co [truncated]
The Linux kernel vulnerability, CVE-2026-72078, affects the ims-pcu driver. The vulnerability class is related to input validation, specifically the failure to verify the control endpoint type of the ims-pcu driver. This oversight could lead to kernel warnings or undefined behavior if a malicious device provides a different endpoint type. The vulnerability has a high potential operational impact, as it co [truncated]
A race condition vulnerability was found in the ims_pcu_reset_device sysfs callback in the Linux kernel. The ims_pcu_reset_device callback calls ims_pcu_execute_command without acquiring the pcu->cmd_mutex, leading to potential data races and corruption of the shared command buffer. This vulnerability could result in data races and corruption of the shared command buffer if triggered concurrently with oth [truncated]
A type confusion vulnerability exists in the Linux kernel's ims-pcu driver when parsing CDC union descriptors. The driver does not verify that the bMasterInterface0 matches the interface being probed, potentially allowing a driver to overwrite the private data of another interface. This issue could lead to security problems if exploited, emphasizing the need for thorough validation and verification of int [truncated]
AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-08-15T06:21:17.123Z and has not been modified since then.

The CVE-2026-72072 vulnerability is a use-after-free issue in the Linux kernel's net/mlx5e: macsec module. When an offloaded MACsec RX SC is deleted, the per-SC metadata_dst is freed, but the RX datapath may still operate on the freed memory. This can lead to potential security risks if not addressed. Linux kernel users and administrators should be aware of this vulnerability and take steps to mitigate it [truncated]
The Linux kernel vulnerability (CVE-2026-72071) is a use-after-free issue in user_event_mm_dup(). This vulnerability arises from the fact that user_event_mm_dup() walks the parent mm's enabler list locklessly under rcu_read_lock() during fork(), without taking event_mutex. The vulnerability can lead to two use-after-frees: one where kfree(enabler) frees the enabler while a reader still dereferences enable [truncated]
The Linux kernel vulnerability CVE-2026-72068 involves a posix-cpu-timers issue. In the update_rlimit_cpu() function, a 32-bit multiplication could cause truncation for RLIMIT_CPU soft limits greater than 4 seconds, leading to premature firing of process CPU timers. The vulnerability has been resolved by applying a u64 cast to ensure accurate conversions.
The Linux kernel has a vulnerability that has been resolved, allowing for a buffer overflow condition. The states_show() function adds CPU hotplug state names into a single sysfs buffer using sprintf(). With enough registered states, this can write past the end of the PAGE_SIZE buffer.

This vulnerability affects Linux kernel users and administrators, who should be aware of this issue and take necessary actions to prevent potential problems. The CVE record was publish [truncated]
The Linux kernel vulnerability CVE-2026-72061 has been resolved in the net: sit module. This vulnerability required CAP_NET_ADMIN in the device netns for changelink. The ipip6_changelink() function operates on at most two netns, dev_net(dev) and the tunnel link netns t->net. They differ once the device is created in or moved to a netns other than the one the request runs in. The rtnl changelink path check [truncated]
The Linux kernel vulnerability CVE-2026-72060 relates to the icssg driver for Texas Instruments Ethernet devices. The icssg_ndo_get_stats64() function was calling emac_get_stat_by_name() unconditionally with FW PA stat names, even if the PA stats block was not present on the hardware. This resulted in thousands of log entries with error messages and corrupted statistics counters.
The Linux kernel has a vulnerability that has been resolved: net: wwan: t7xx: destroy DMA pool on CLDMA late init failure. The t7xx_cldma_late_init() function creates md_ctrl->gpd_dmapool before initializing the TX and RX rings. If any ring initialization fails, the error path frees the already initialized rings but leaves the DMA pool allocated. Destroy md_ctrl->gpd_dmapool on the late-init failure path [truncated]
Linux kernel vulnerability CVE-2026-72058 resolved: net: ixp4xx_hss: fix duplicate HDLC netdev allocation. The vulnerability was addressed by allocating the HDLC netdev only once and assigning the same object to port->netdev, preventing duplicate HDLC netdev allocation in the ixp4xx_hss_probe() function. This change ensures that the registered netdev is the same object that is unregistered and freed on re [truncated]
A vulnerability in the Linux kernel's net/sched: act_ct has been resolved. The tcf_ct_handle_fragments() function calls nf_ct_handle_fragments() without saving and restoring skb->cb, which can lead to lost qdisc metadata. This oversight can cause issues such as WARN_ON_ONCE() triggers in qdisc_pkt_segs() when panic_on_warn is enabled. The fix involves saving and restoring the full tc_skb_cb around nf_ct_h [truncated]
A resource leak vulnerability was found in the Linux kernel's net: ena driver. The create_queues_with_size_backoff() function creates XDP TX queues before setting up the regular TX path. If the subsequent allocation or creation of regular TX queues fails, the error handling paths omit the teardown of the XDP TX queues, leading to a resource leak. The bug was first flagged by an experimental analysis tool [truncated]
The Linux kernel vulnerability CVE-2026-72055 has been resolved, affecting the net: ip6_vti module. The issue requires CAP_NET_ADMIN in the device netns for changelink operations.
