The remote NewStart CGSL host, running version MAIN 7.02, has kernel packages installed that are affected by multiple vulnerabilities:

  - In the Linux kernel, the following vulnerability has been resolved: xen: fix UAF in     dmabuf_exp_from_pages() [dma_buf_fd() fixes; no preferences regarding the tree it goes through - up to xen     folks] As soon as we'd inserted a file reference into descriptor table, another thread could close it.
    That's fine for the case when all we are doing is returning that descriptor to userland (it's a race, but     it's a userland race and there's nothing the kernel can do about it). However, if we follow fd_install()     with any kind of access to objects that would be destroyed on close (be it the struct file itself or     anything destroyed by its ->release()), we have a UAF. dma_buf_fd() is a combination of reserving a     descriptor and fd_install(). gntdev dmabuf_exp_from_pages() calls it and then proceeds to access the     objects destroyed on close - starting with gntdev_dmabuf itself. Fix that by doing reserving descriptor     before anything else and do fd_install() only when everything had been set up. (CVE-2025-38595)

  - In the Linux kernel, the following vulnerability has been resolved: md: fix kmemleak of rdev->serial If     kobject_add() is fail in bind_rdev_to_array(), 'rdev->serial' will be alloc not be freed, and kmemleak     occurs. unreferenced object 0xffff88815a350000 (size 49152): comm mdadm, pid 789, jiffies 4294716910 hex     dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00     00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc f773277a): [<0000000058b0a453>]     kmemleak_alloc+0x61/0xe0 [<00000000366adf14>] __kmalloc_large_node+0x15e/0x270 [<000000002e82961b>]

  - In the Linux kernel, the following vulnerability has been resolved: dma-direct: Leak pages on     dma_set_decrypted() failure On TDX it is possible for the untrusted host to cause set_memory_encrypted()     or set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared.
    Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page     allocator, which could lead to functional or security issues. DMA could free decrypted/shared pages if     dma_set_decrypted() fails. This should be a rare case. Just leak the pages in this case instead of freeing     them. (CVE-2024-35939)

  - In the Linux kernel, the following vulnerability has been resolved: tipc: fix UAF in error path Sam Page     (sam4k) working with Trend Micro Zero Day Initiative reported a UAF in the tipc_buf_append() error path:

  - In the Linux kernel, the following vulnerability has been resolved: gpiolib: cdev: fix uninitialised kfifo     If a line is requested with debounce, and that results in debouncing in software, and the line is     subsequently reconfigured to enable edge detection then the allocation of the kfifo to contain edge events     is overlooked. This results in events being written to and read from an uninitialised kfifo. Read events     are returned to userspace. Initialise the kfifo in the case where the software debounce is already active.
    (CVE-2024-36898)

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