Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2057 advisory.

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

iommu/vt-d: Clear Present bit before tearing down context entry (CVE-2026-45944)

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

mm/vmalloc: take vmap_purge_lock in shrinker (CVE-2026-46093)

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

af_unix: Drop all SCM attributes for SOCKMAP. (CVE-2026-53005)

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

fs/ntfs3: fix missing run load for vcn0 in attr_data_get_block_locked() (CVE-2026-53027)

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

vsock/virtio: fix zerocopy completion for multi-skb sends (CVE-2026-53365)

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

NFSv4/flexfiles: reject zero filehandle version count (CVE-2026-53392)

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

fbdev: fbcon: fix out-of-bounds read in err_out of fbcon_do_set_font()

When fbcon_do_set_font() fails (e.g., due to a memory allocation failureinside vc_resize() under heavy memory pressure), it jumps to the `err_out`label to roll back the console state. However, the current rollback logicforgets to restore the `hi_font` state, leading to a severe state machinecorruption.

Earlier in the function, `set_vc_hi_font()` might be called to change`vc->vc_hi_font_mask` and mutate the screen buffer. If `vc_resize()`subsequently fails, the `err_out` path restores `vc_font.charcount`but entirely skips rolling back the `vc_hi_font_mask` and the screenbuffer.

This mismatch leaves the terminal in a desynchronized state. Because`vc_hi_font_mask` remains set, the VT subsystem will still acceptcharacter indices greater than 255 from userspace and write them to thescreen buffer. Subsequent rendering calls (e.g., `fbcon_putcs()`) willthen use these inflated indices to access the reverted, 256-characterfont array, leading to a deterministic out-of-bounds read and potentialkernel memory disclosure.

Fix this by adding the missing rollback logic for the `hi_font` maskand screen buffer in the error path.
(CVE-2026-53402)

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

vsock/virtio: bind uarg before filling zerocopy skb (CVE-2026-63970)

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

tcp: fix stale per-CPU tcp_tw_isn leak enabling ISN prediction

Blamed commit moved the TIME_WAIT-derived ISN from the skb controlblock to a per-CPU variable, assuming the value would always be consumedby tcp_conn_request() for the same packet that wrote it. That assumptionis violated by multiple drop paths between the producer(__this_cpu_write(tcp_tw_isn, isn) in tcp_v{4,6}_rcv()) and the consumer(tcp_conn_request()):

- min_ttl / min_hopcount check- xfrm policy check- tcp_inbound_hash() MD5/AO mismatch- tcp_filter() eBPF/SO_ATTACH_FILTER drop- th->syn && th->fin discard in tcp_rcv_state_process() TCP_LISTEN- psp_sk_rx_policy_check() in tcp_v{4,6}_do_rcv()- tcp_checksum_complete() in tcp_v{4,6}_do_rcv()- tcp_v{4,6}_cookie_check() returning NULL

When a packet is dropped on any of these paths, tcp_tw_isn is left set.

The next SYN processed on the same CPU then consumes the non zero value intcp_conn_request(), receiving a potentially predictable ISN.

This patch moves back tcp_tw_isn to skb->cb[], getting rid of the per-cpuvariable.

Note that tcp_v{4,6}_fill_cb() do not set it.

Very litle impact on overall code size/complexity:

netfilter: ebtables: move to two-stage removal scheme (CVE-2026-64077)

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

xfs: fail recovery on a committed log item with no regions

If the first op of a transaction is a bare transaction header(len == sizeof(struct xfs_trans_header)), xlog_recover_add_to_trans()adds an item but no region, leaving it on r_itemq with ri_cnt == 0 andri_buf == NULL.

The header can be split across op records, so later ops may still addregions; the item is only invalid if the transaction commits with none.The runtime commit path never emits such a transaction, so this onlyhappens on a crafted log. It came from an AI-assisted code audit of therecovery parser.

xlog_recover_reorder_trans() calls ITEM_TYPE() on the item, which reads*(unsigned short
*)item->ri_buf[0].iov_base and faults on the NULLri_buf. Reject it there, before the commit handlers that also readri_buf[0].

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

netfilter: ipset: fix race between dump and ip_set_list resize (CVE-2026-64189)

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

bpf: Reject BPF_MAP_TYPE_INODE_STORAGE creation if BPF LSM is uninitialized

When CONFIG_BPF_LSM=y is set, BPF inode storage maps(BPF_MAP_TYPE_INODE_STORAGE) are compiled into the kernel. However,if the BPF LSM is not explicitly enabled at boot time (e.g. omittedfrom the lsm= boot parameter), lsm_prepare() is never executed forthe BPF LSM.

Consequently, the BPF inode security blob offset(bpf_lsm_blob_sizes.lbs_inode) is never initialized and remains atits default compiled size of 8 bytes instead of being updated to avalid offset past the reserved struct rcu_head (typically 16 bytesor more).

When a privileged user creates and updates a BPF_MAP_TYPE_INODE_STORAGEmap, bpf_inode() evaluates inode->i_security + 8. This erroneouslyaliases the struct rcu_head.func callback pointer at the beginningof the inode->i_security blob. During subsequent map element cleanupor inode destruction, writing NULL to owner_storage clears the queuedRCU callback pointer. When rcu_do_batch() later executes the queuedcallback, it attempts an instruction fetch at address 0x0, triggeringan immediate kernel panic.

Fix this by introducing a global bpf_lsm_initialized boolean flagmarked with __ro_after_init. Set this flag to true inside bpf_lsm_init()when the LSM framework successfully registers the BPF LSM. Gate mapallocation in inode_storage_map_alloc() on this flag, returning-EOPNOTSUPP if the BPF LSM is in turn uninitialized.

This fail-fast approach prevents userspace from allocating inodestorage maps when the supporting BPF LSM infrastructure is absent,avoiding zombie map states. (CVE-2026-64192)

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

perf/core: Detach event groups during remove_on_exec

perf_event_remove_on_exec() removes events by callingperf_event_exit_event(). For top-level events, this removes the event fromthe context with DETACH_EXIT only.

This can leave inconsistent group state when a removed event is a groupleader and the group contains siblings without remove_on_exec. If the groupwas active, the surviving siblings can remain active and attached to theremoved leader's sibling list, but are no longer represented by a validgroup leader on the PMU context active lists.

A later close of the removed leader uses DETACH_GROUP and can promote thestill-active siblings from this stale group state. The next schedule-in canthen add an already-linked active_list entry again, corrupting the PMUcontext active list.

With DEBUG_LIST enabled, this is caught as a list_add double-add inmerge_sched_in().

Fix this by detaching group relationships when remove_on_exec removes anevent. This preserves the existing task-exit and revoke behavior, whileensuring surviving siblings are ungrouped before the removed event leavesthe context. (CVE-2026-64556)

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

posix-cpu-timers: Prevent UAF caused by non-leader exec() race (CVE-2026-64560)

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

KVM: x86: Check for invalid/obsolete root *after* making MMU pages available

Check for a stale page fault, i.e. for an invalid and/or obsolete root,after making MMU pages available for the shadow MMU. If reclaiming shadowpages zaps an in-use root, i.e. marks it invalid, then KVM will attempt tomap memory into an invalid root. On its own, populating an invalid root isfine, but because child shadow pages inherit their parent's role, anychildren created during the map/fetch will be created as invalid pages,thus violating KVM's invariant that invalid pages are never on the list ofactive MMU pages.

Note, the underlying flaw has existed since KVM first started trackinginvalid roots in 2008 (commit 2e53d63acba7, KVM: MMU: ignore zapped rootpagetables), but the true badness only came along in 2020 (Linux 5.9)with the invariant that invalid shadow pages can't be on the list ofactive pages.

Note #2, inheriting role.invalid when creating child shadow pages is alsofar from ideal; that flaw will be addressed separately. (CVE-2026-64561)
