In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Fix use-after-free of CPU job query arrays on error path The CPU job ioctl's fail label calls kvfree() on cpu_job's timestamp and performance query arrays after v3d_job_cleanup(), which drops the job's last reference and frees cpu_job. Reading cpu_job at that point is a use-after-free. Also, on the early v3d_job_init() failure path, it is a NULL dereference, since v3d_job_deallocate() zeroes the local pointer. In the success path, the arrays are released from the scheduler's .free_job callback, but on the error path, they are freed manually, as the job was never pushed to the scheduler. While the success path deals with this correctly, the fail path doesn't. On top of that, the manual kvfree() calls only free the array storage; they don't drm_syncobj_put() the per-query syncobjs that v3d_timestamp_query_info_free() and v3d_performance_query_info_free() release on the success path. So the same fail path that triggers the use-after-free also leaks one syncobj reference per query. Unify the CPU job teardown into the CPU job's kref destructor, mirroring v3d_render_job_free(). The scheduler's .free_job slot reverts to the generic v3d_sched_job_free() and the fail label drops the manual kvfree() calls, leaving a single teardown path that is reached from both the scheduler and the ioctl error path. That removes the use-after-free, the NULL dereference, and the syncobj leak by construction.

The remote Ubuntu 24.04 LTS / Pro Realtime 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8781-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

An update of the linux package has been released.

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

  - drm/v3d: Fix use-after-free of CPU job query arrays on error path The CPU job ioctl's fail label calls     kvfree() on cpu_job's timestamp and performance query arrays after v3d_job_cleanup(), which drops the     job's last reference and frees cpu_job. Reading cpu_job at that point is a use-after-free. Also, on the     early v3d_job_init() failure path, it is a NULL dereference, since v3d_job_deallocate() zeroes the local     pointer. In the success path, the arrays are released from the scheduler's .free_job callback, but on the     error path, they are freed manually, as the job was never pushed to the scheduler. While the success path     deals with this correctly, the fail path doesn't. On top of that, the manual kvfree() calls only free the     array storage; they don't drm_syncobj_put() the per-query syncobjs that v3d_timestamp_query_info_free()     and v3d_performance_query_info_free() release on the success path. So the same fail path that triggers the     use-after-free also leaks one syncobj reference per query. Unify the CPU job teardown into the CPU job's     kref destructor, mirroring v3d_render_job_free(). The scheduler's .free_job slot reverts to the generic     v3d_sched_job_free() and the fail label drops the manual kvfree() calls, leaving a single teardown path     that is reached from both the scheduler and the ioctl error path. That removes the use-after-free, the     NULL dereference, and the syncobj leak by construction. (CVE-2026-64099)

Note that Nessus relies on the presence of the package as reported by the vendor.
