In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl() Two error handling issues exist in xe_exec_queue_create_ioctl(): 1. When xe_hw_engine_group_add_exec_queue() fails, the error path jumps to put_exec_queue which skips xe_exec_queue_kill(). If the VM is in preempt fence mode, xe_vm_add_compute_exec_queue() has already added the queue to the VM's compute exec queue list. Skipping the kill leaves the queue on that list, leading to a dangling pointer after the queue is freed. 2. When xa_alloc() fails after xe_hw_engine_group_add_exec_queue() has succeeded, the error path does not call xe_hw_engine_group_del_exec_queue() to remove the queue from the hw engine group list. The queue is then freed while still linked into the hw engine group, causing a use-after-free. Fix both by: - Changing the xe_hw_engine_group_add_exec_queue() failure path to jump to kill_exec_queue so that xe_exec_queue_kill() properly removes the queue from the VM's compute list. - Adding a del_hw_engine_group label before kill_exec_queue for the xa_alloc() failure path, which removes the queue from the hw engine group before proceeding with the rest of the cleanup. (cherry picked from commit 37c831f401746a45d510b312b0ed7a77b1e06ec8)

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:42919 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * kernel: crypto: af_alg - zero initialize memory allocated via sock_kmalloc (CVE-2025-71113)

    * kernel: Linux kernel: Denial of Service due to memory leak in tpm2_load_cmd (CVE-2025-71147)

    * kernel: flex_proportions: make fprop_new_period() hardirq safe (CVE-2026-23168)

    * kernel: cxl/port: Fix use after free of parent_port in cxl_detach_ep() (CVE-2026-31530)

    * kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete (CVE-2026-46116)

    * kernel: fanotify: fix false positive on permission events (CVE-2026-46150)

    * kernel: drm: Set old handle to NULL before prime swap in change_handle (CVE-2026-46215)

    * kernel: drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl() (CVE-2026-52976)

    * kernel: drm/xe/dma-buf: fix UAF with retry loop (CVE-2026-52950)

    * kernel: ice: fix double-free of tx_buf skb (CVE-2026-53009)

    * kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp (CVE-2026-53071)

    * kernel: can: bcm: thrtimer use-after-free during RX operation teardown ()

    Bug Fix(es) and Enhancement(s):

    * nfsd_file slab cache objects remaining on kmem_cache_shutdown during nfsd teardown while running     bz1477872 testcase (JIRA:RHEL-173103)

    * tools/lib/perf/Makefile: libperf includes appended after CFLAGS causes parallel build race, breaking     kernel builds [rhel-10.2.z] (JIRA:RHEL-183975)

    * [RHEL10-debug]: BUG: KASAN: slab-use-after-free in __pv_queued_spin_lock_slowpath [rhel-10.2.z]     (JIRA:RHEL-186311)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
