In the Linux kernel, the following vulnerability has been resolved: smb: client: honor forceuid/forcegid when mapping SIDs to uid/gid When the administrator mounts with forceuid or forcegid (uid=/gid= mount options), they expect all files to appear owned by the specified user/group. However, several code paths unconditionally called sid_to_id() to overwrite cf_uid/cf_gid with server-provided values, ignoring the administrator's explicit override: - smb311_posix_info_to_fattr() (stat via POSIX extensions) - cifs_posix_to_fattr() (readdir via POSIX extensions) - parse_sec_desc() (CIFS ACL ownership mapping) This allowed an untrusted server to dictate local file ownership even when the mount was configured to force specific uid/gid values. Fix all three call sites to check CIFS_MOUNT_OVERR_UID and CIFS_MOUNT_OVERR_GID before calling sid_to_id(), following the same pattern already used by cifs_unix_basic_to_fattr() for unix extensions.

  - In the Linux kernel, the following vulnerability has been resolved: net/sched: act_mirred: use the backlog     for mirred ingress The test Davide added in commit ca22da2fbd69 (act_mirred: use the backlog for nested     calls to mirred ingress) hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv ->     tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that     if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which     generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks     is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress ->     ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the     backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround     does not seem to address the issue.

  - In the Linux kernel, the following vulnerability has been resolved: vfs: Don't evict inode under the inode     lru traversing context The inode reclaiming process(See function prune_icache_sb) collects all reclaimable     inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try     getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by     function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode     lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru     traversing context, deadlock problems may happen. Case 1: In function ext4_evict_inode(), the ea inode     lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting     context like this: 1. File A has inode i_reg and an ea inode i_ea 2. getfattr(A, xattr_buf) // i_ea is     added into lru // lru->i_ea 3. Then, following three processes running like this: PA PB echo 2 >     /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg     prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state     inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink =     0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode     ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast

File A has inode ia and a     xattr(with inode ixa), regular file B has inode ib and a xattr. 2. getfattr(A, xattr_buf) // ixa is added     into lru // lru->ixa 3.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: avoid uninit memory read     in ath9k_htc_rx_msg() syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], for     ioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() with pkt_len = 0 but     ath9k_hif_usb_rx_stream() uses __dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption that     pkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skb with uninitialized memory and     ath9k_htc_rx_msg() is reading from uninitialized memory. Since bytes accessed by ath9k_htc_rx_msg() is not     known until ath9k_htc_rx_msg() is called, it would be difficult to check minimal valid pkt_len at if     (pkt_len > 2 * MAX_RX_BUF_SIZE) { line in ath9k_hif_usb_rx_stream(). We have two choices. One is to     workaround by adding __GFP_ZERO so that ath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to     let ath9k_htc_rx_msg() validate pkt_len before accessing. This patch chose the latter. Note that I'm not     sure threshold condition is correct, for I can't find details on possible packet length used by this     protocol. (CVE-2022-50709)

    __memcpy+0x110/0x260 read_kcore+0x584/0x778 proc_reg_read+0xb4/0xe4 During early boot, memblock reserves     the pages for the ramoops reserved memory node in DT that would otherwise be part of the direct lowmem     mapping. Pstore's ram backend reuses those reserved pages to change the memory type (writeback or non-     cached) by passing the pages to vmap() (see pfn_to_page() usage in persistent_ram_vmap() for more details)     with specific flags. When read_kcore() starts iterating over the vmalloc region, it runs over the virtual     address that vmap() returned for ramoops. In aligned_vread() the virtual address is passed to     vmalloc_to_page() which returns the page struct for the reserved lowmem area. That lowmem page is passed     to kmap_atomic(), which effectively calls page_to_virt() that assumes a lowmem page struct must be     directly accessible with __va() and friends. These pages are mapped via vmap() though, and the lowmem     mapping was never made, so accessing them via the lowmem virtual address oopses like above. Let's side-     step this problem by passing VM_IOREMAP to vmap(). This will tell vread() to not include the ramoops     region in the kcore. Instead the area will look like a bunch of zeros. The alternative is to teach kmap()     about vmalloc areas that intersect with lowmem. Presumably such a change isn't a one-liner, and there     isn't much interest in inspecting the ramoops region in kcore files anyway, so the most expedient route is     taken for now. (CVE-2022-50849)

  - In the Linux kernel, the following vulnerability has been resolved: hwrng: amd - Fix PCI device refcount     leak for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it     will increase the reference count for the returned pci_dev and also decrease the reference count for the     input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to     call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() for the normal and error     path. (CVE-2022-50868)

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/srp: Do not call scsi_done() from     srp_abort() After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler callback, it performs     one of the following actions: * Call scsi_queue_insert(). * Call scsi_finish_command(). * Call     scsi_eh_scmd_add(). Hence, SCSI abort handlers must not call scsi_done(). Otherwise all the above actions     would trigger a use-after-free. Hence remove the scsi_done() call from srp_abort(). Keep the     srp_free_req() call before returning SUCCESS because we may not see the command again if SUCCESS is     returned. (CVE-2023-52515)

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.

  - smb: client: honor forceuid/forcegid when mapping SIDs to uid/gid When the administrator mounts with     forceuid or forcegid (uid=/gid= mount options), they expect all files to appear owned by the specified     user/group. However, several code paths unconditionally called sid_to_id() to overwrite cf_uid/cf_gid with     server-provided values, ignoring the administrator's explicit override: - smb311_posix_info_to_fattr()     (stat via POSIX extensions) - cifs_posix_to_fattr() (readdir via POSIX extensions) - parse_sec_desc()     (CIFS ACL ownership mapping) This allowed an untrusted server to dictate local file ownership even when     the mount was configured to force specific uid/gid values. Fix all three call sites to check     CIFS_MOUNT_OVERR_UID and CIFS_MOUNT_OVERR_GID before calling sid_to_id(), following the same pattern     already used by cifs_unix_basic_to_fattr() for unix extensions. (CVE-2026-97561)

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