Amazon Linux 2023 : bpftool6.18, kernel6.18, kernel6.18-devel (ALAS2023-2026-2045)

high Nessus Plugin ID 337207

Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2045 advisory.

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

iommu/vt-d: Fix race condition during PASID entry replacement (CVE-2026-45945)

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:

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:

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:

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)
