    Here is another different caller causing the same issue because of the same reason. So we should protect     it with sk_callback_lock read lock because the writer side in the sk_psock_drop() uses     write_lock_bh(&sk->sk_callback_lock);. To avoid errors that could happen in future, I move those two     pairs of lock into the sk_psock_data_ready(), which is suggested by John Fastabend. (CVE-2024-36938)

As for now, the maximal read size for kvec iter is only     limited by fc->max_read. For virtio-fs, max_read is UINT_MAX, so fuse_direct_io() doesn't split the 10MB     buffer. It saves the address and the size of the 10MB-sized buffer in out_args[0] of a fuse request and     passes the fuse request to virtio_fs_wake_pending_and_unlock(). 4) virtio_fs_wake_pending_and_unlock()     uses virtio_fs_enqueue_req() to queue the request. Because virtiofs need DMA-able address, so     virtio_fs_enqueue_req() uses kmalloc() to allocate a bounce buffer for all fuse args, copies these args     into the bounce buffer and passed the physical address of the bounce buffer to virtiofsd. The total length     of these fuse args for the passed fuse request is about 10MB, so copy_args_to_argbuf() invokes kmalloc()     with a 10MB size parameter and it triggers the warning in __alloc_pages(): if (WARN_ON_ONCE_GFP(order >     MAX_PAGE_ORDER, gfp)) return NULL; 5) virtio_fs_enqueue_req() will retry the memory allocation in a     kworker, but it won't help, because kmalloc() will always return NULL due to the abnormal size and     finit_module() will hang forever. A feasible solution is to limit the value of max_read for virtio-fs, so     the length passed to kmalloc() will be limited. However it will affect the maximal read size for normal     read. And for virtio-fs write initiated from kernel, it has the similar problem but now there is no way to     limit fc->max_write in kernel. So instead of limiting both the values of max_read and max_write in kernel,     introducing use_pages_for_kvec_io in fuse_conn and setting it as true in virtiofs. When     use_pages_for_kvec_io is enabled, fuse will use pages instead of pointer to pass the KVEC_IO data. After     switching to pages for KVEC_IO data, these pages will be used for DMA through virtio-fs. If these pages     are backed by vmalloc(), {flush|invalidate}_kernel_vmap_range() are necessary to flush or invalidate the     cache before the DMA operation. So add two new fields in fuse_args_pages to record the base address of     vmalloc area and the condition indicating whether invalidation is needed. Perform the flush in     fuse_get_user_pages() for write operations and the invalidation in fuse_release_user_pages() for read     operations. It may seem necessary to introduce another fie ---truncated--- (CVE-2024-53219)

  - In the Linux kernel, the following vulnerability has been resolved: acct: perform last write from     workqueue In [1] it was reported that the acct(2) system call can be used to trigger NULL deref in cases     where it is set to write to a file that triggers an internal lookup. This can e.g., happen when pointing     acc(2) to /sys/power/resume. At the point the where the write to this file happens the calling task has     already exited and called exit_fs(). A lookup will thus trigger a NULL-deref when accessing current->fs.
    Reorganize the code so that the the final write happens from the workqueue but with the caller's     credentials. This preserves the (strange) permission model and has almost no regression risk. This api     should stop to exist though. (CVE-2025-21846)

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