The remote Ubuntu 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8727-1 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 A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges.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.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-100551 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    NFSD: Fix SECINFO_NO_NAME decode error cleanup

    nfsd4_decode_secinfo_no_name() currently initializes sin_exp after     decoding sin_style. If the XDR stream is truncated, the decoder returns     nfserr_bad_xdr before sin_exp is initialized.

    Since commit 3fdc54646234 (NFSD: Reduce amount of struct     nfsd4_compoundargs that needs clearing), the inline iops array is not     cleared between RPC calls. A failed SECINFO_NO_NAME decode can therefore     leave sin_exp holding stale union contents from a previous operation.

    The error response path still invokes nfsd4_secinfo_no_name_release(),     which calls exp_put() on a non-NULL sin_exp.

    Initialize sin_exp before the first failable decode step, matching     nfsd4_decode_secinfo().

    In the Linux kernel, the following vulnerability has been resolved:

    virtiofs: fix UAF on submount umount

    iput() called from fuse_release_end() can Oops if the super block hasalready been destroyed.  Normally     this is prevented by waiting fornum_waiting to go down to zero before commencing with super block     shutdown.

    This only works, however, for the last submount instance, as the waitcounter is per connection, not per     superblock.

    Revert to using synchronous release requests for the auto_submounts case,which is virtiofs only at this     time. (CVE-2026-53381)

    In the Linux kernel, the following vulnerability has been resolved:

    vc_screen: fix null-ptr-deref in vcs_notifier() during concurrent vcs_write

    A KASAN null-ptr-deref was observed in vcs_notifier():

    BUG: KASAN: null-ptr-deref in vcs_notifier+0x98/0x130Read of size 2 at addr qmp_cmd_name:
    qmp_capabilities, arguments: {}

    The issue is a race condition in vcs_write(). When the console_lock istemporarily dropped (to copy data     from userspace), the vc_data pointerobtained from vcs_vc() may become stale. After re-acquiring the     lock,vcs_vc() is called again to re-validate the pointer. If the vc has beendeallocated in the meantime,     vcs_vc() returns NULL, and the while loopbreaks (with written > 0). However, after the loop,     vcs_scr_updated(vc)is still called with the now-NULL vc pointer, leading to a null pointerdereference in     the notifier chain (vcs_notifier dereferences param->vc).

    Fix this by adding a NULL check for vc before calling vcs_scr_updated(). (CVE-2026-53385)

    In the Linux kernel, the following vulnerability has been resolved:

    nfsd: fix posix_acl leak on SETACL decode failure (CVE-2026-53397)

    In the Linux kernel, the following vulnerability has been resolved:

    NFSD: Fix SECINFO_NO_NAME decode error cleanup (CVE-2026-53398)

    In the Linux kernel, the following vulnerability has been resolved:

    fbdev: Fix fb_new_modelist to prevent null-ptr-deref in fb_videomode_to_var

    info->var, a framebuffer's current mode, is expected to have a matchingentry in info->modelist.
    var_to_display() relies on this and treats afailed fb_match_mode() as This should not happen.
    fb_set_var() keeps ittrue by adding the mode to the list on every change, anddo_register_framebuffer()     does the same at registration.

    store_modes() replaces the modelist from userspace. fb_new_modelist()validates the new modes but does not     check that info->var still has amatch. It relies on fbcon_new_modelist() to re-point consoles, but     thatonly handles consoles mapped to the framebuffer. With fbcon unbound thereare none, so info->var is     left describing a mode that is no longer in thelist.

    A later console takeover runs var_to_display(), where fb_match_mode()returns NULL and leaves     fb_display[i].mode NULL. fbcon_switch() passes itto display_to_var(), and fb_videomode_to_var()     dereferences the NULL mode.

    Keep the current mode in the list in fb_new_modelist(), the same wayfb_set_var() does. (CVE-2026-53403)

    In the Linux kernel, the following vulnerability has been resolved:

    KVM: SVM: Fix page overflow in sev_dbg_crypt() for ENCRYPT path (CVE-2026-63794)

    In the Linux kernel, the following vulnerability has been resolved:

    i2c: stub: Reject I2C block transfers with invalid length

    The I2C_SMBUS_I2C_BLOCK_DATA case in stub_xfer() uses data->block[0]as the transfer length. The existing     check only clamps it to avoidoverrunning the chip->words[256] register array, but does not validateit     against I2C_SMBUS_BLOCK_MAX (32), which is the limit of the unioni2c_smbus_data.block buffer (34 bytes     total). The driver is adevelopment/test tool (CONFIG_I2C_STUB=m, not built by default)that must be loaded     with a chip_addr= parameter.

    A local user with access to /dev/i2c-* can issue an I2C_SMBUS ioctlwith I2C_SMBUS_I2C_BLOCK_DATA and     data->block[0] > 32, causingstub_xfer() to read or write past the end of the unioni2c_smbus_data.block     buffer:

    BUG: KASAN: stack-out-of-bounds in stub_xfer (drivers/i2c/i2c-stub.c:223)Read of size 1 at addr     ffff88800abcfd92 by task exploit/81Call Trace:<TASK>stub_xfer (drivers/i2c/i2c-stub.c:223)__i2c_smbus_xfer     (drivers/i2c/i2c-core-smbus.c:593)i2c_smbus_xfer (drivers/i2c/i2c-core-smbus.c:536)i2cdev_ioctl_smbus     (drivers/i2c/i2c-dev.c:391)i2cdev_ioctl (drivers/i2c/i2c-dev.c:478)__x64_sys_ioctl     (fs/ioctl.c:583)do_syscall_64 (arch/x86/entry/syscall_64.c:94)entry_SYSCALL_64_after_hwframe     (arch/x86/entry/entry_64.S:130)</TASK>

    The bug exists because i2c-stub implements .smbus_xfer directly,bypassing the I2C_SMBUS_BLOCK_MAX     validation ini2c_smbus_xfer_emulated(). The I2C_SMBUS_BLOCK_DATA case in the samefunction correctly     validates against I2C_SMBUS_BLOCK_MAX, but theI2C_SMBUS_I2C_BLOCK_DATA case does not.

    Fix by rejecting transfers with data->block[0] == 0 ordata->block[0] > I2C_SMBUS_BLOCK_MAX with -EINVAL,     consistent withboth the I2C_SMBUS_BLOCK_DATA case in the same function and theI2C_SMBUS_I2C_BLOCK_DATA     validation in i2c_smbus_xfer_emulated(). (CVE-2026-64191)

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1792762308 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: fix race between     dump and ip_set_list resize The release path of ip_set_dump_do() and ip_set_dump_done() read     inst->ip_set_list via ip_set_ref_netlink(), a plain rcu_dereference_raw() of the array pointer. These run     from netlink_recvmsg() without the nfnl mutex and without an RCU read-side critical section. A concurrent     ip_set_create() can grow the array: it publishes the new array, calls synchronize_net() and then kvfree()s     the old one. Since the dump paths read the array outside any RCU reader, synchronize_net() does not wait     for them and the old array can be freed while they still index into it, causing a use-after-free. The     dumped set itself stays pinned via set->ref_netlink, so only the array load needs protecting. Take     rcu_read_lock() around it, matching ip_set_get_byname() and __ip_set_put_byindex(). BUG: KASAN: slab-use-     after-free in ip_set_dump_do (net/netfilter/ipset/ip_set_core.c:1697) Read of size 8 at addr     ffff88800b5c4018 by task exploit/150 Call Trace: ... kasan_report (mm/kasan/report.c:595) ip_set_dump_do     (net/netfilter/ipset/ip_set_core.c:1697) netlink_dump (net/netlink/af_netlink.c:2325) netlink_recvmsg     (net/netlink/af_netlink.c:1976) sock_recvmsg (net/socket.c:1159) __sys_recvfrom (net/socket.c:2315) ...

  - In the Linux kernel, the following vulnerability has been resolved: dm log: fix out-of-bounds write due to     region_count overflow The local variable region_count in create_log_context() is declared as unsigned int     (32-bit), but dm_sector_div_up() returns sector_t (64-bit). When a device-mapper target has a sufficiently     large ti->len with a small region_size, the division result can exceed UINT_MAX. The truncated value is     then used to calculate bitset_size, causing clean_bits, sync_bits, and recovering_bits to be allocated far     smaller than needed for the actual number of regions. Subsequent log operations (log_set_bit,     log_clear_bit, log_test_bit) use region indices derived from the full untruncated region space, causing     out-of-bounds writes to kernel heap memory allocated by vmalloc. This can be reproduced by creating a     mirror target whose region_count overflows 32 bits: dmsetup create bigzero --table '0 8589934594 zero'     dmsetup create mymirror --table '0 8589934594 mirror \ core 2 2 nosync 2 /dev/mapper/bigzero 0 \     /dev/mapper/bigzero 0' The status output confirms the truncation (sync_count=1 instead of 4294967297,     because 0x100000001 was truncated to 1): $ dmsetup status mymirror 0 8589934594 mirror 2 254:1 254:1     1/4294967297 ... This leads to a kernel crash in core_in_sync: BUG: scheduling while atomic: (udev-     worker)/9150/0x00000000 RIP: 0010:core_in_sync+0x14/0x30 [dm_log] CR2: 0000000000000008 Fixing recursive     fault but reboot is needed! Fix by widening the local region_count to sector_t and adding an explicit     overflow check before the value is assigned to lc->region_count. (CVE-2026-53059)

  - In the Linux kernel, the following vulnerability has been resolved: ipv6: fix fib6 walker UAF on seq stop     ipv6_route_iter_active() treats a walker in FWS_U at the table root as already unlinked. fib6_del_route()     can move a still-linked walker into that same state when the current leaf is the last route at the root,     so ipv6_route_native_seq_stop() skips fib6_walker_unlink(). The seq private object can then be freed while     it remains on net->ipv6.fib6_walkers. A later route deletion walks the dangling list and uses the freed     walker. Use the list head as membership state and reinitialize it when unlinking. Keep the existing     w->node check so a never-started iterator with a zeroed private object is not treated as linked. The same     stop helper is used by /proc/net/ipv6_route and by the BPF ipv6_route iterator. The BPF show path only     widens the race. (CVE-2026-97940)

  - In the Linux kernel, the following vulnerability has been resolved: fanotify: fix false positive on     permission events fsnotify_get_mark_safe() may return false for a mark on an unrelated group, which     results in bypassing the permission check. Fix by skipping over detached marks that are not in the current     group. (CVE-2026-46150)

  - In the Linux kernel, the following vulnerability has been resolved: nvmet: fix NULL pointer dereference in     nvmet_execute_identify_ns_zns() When a host issues an Identify command with CNS 05h (I/O Command Set     specific Identify Namespace) and CSI 02h (ZNS) targeting a file-backed namespace,     nvmet_execute_identify_ns_zns() calls bdev_is_zoned() on req->ns->bdev. A file-backed namespace has no     block device, so req->ns->bdev is NULL and bdev_is_zoned() dereferences it, oopsing. The I/O command set     is selected by the host-supplied CSI field and the command is routed here whenever CONFIG_BLK_DEV_ZONED is     enabled, independent of the namespace backing type, so any file-backed namespace is exposed. Reject the     command with Invalid Field when the namespace is not backed by a block device. (CVE-2026-90228)
