kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

pinctrl: mcp23s08: Fix sleeping in atomic context due to regmap locking

If a device uses MCP23xxx IO expander to receive IRQs, the following bug can happen:

BUG: sleeping function called from invalid context at kernel/locking/mutex.c:283 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, ... preempt_count: 1, expected: 0 ... Call Trace: ... __might_resched+0x104/0x10e __might_sleep+0x3e/0x62 mutex_lock+0x20/0x4c regmap_lock_mutex+0x10/0x18 regmap_update_bits_base+0x2c/0x66 mcp23s08_irq_set_type+0x1ae/0x1d6 __irq_set_trigger+0x56/0x172 __setup_irq+0x1e6/0x646 request_threaded_irq+0xb6/0x160 ...

We observed the problem while experimenting with a touchscreen driver which used MCP23017 IO expander (I2C).

The regmap in the pinctrl-mcp23s08 driver uses a mutex for protection from concurrent accesses, which is the default for regmaps without .fast_io, .disable_locking, etc.

mcp23s08_irq_set_type() calls regmap_update_bits_base(), and the latter locks the mutex.

However, __setup_irq() locks desc->lock spinlock before calling these functions. As a result, the system tries to lock the mutex whole holding the spinlock.

It seems, the internal regmap locks are not needed in this driver at all. mcp->lock seems to protect the regmap from concurrent accesses already, except, probably, in mcp_pinconf_get/set.

mcp23s08_irq_set_type() and mcp23s08_irq_mask/unmask() are called under chip_bus_lock(), which calls mcp23s08_irq_bus_lock(). The latter takes mcp->lock and enables regmap caching, so that the potentially slow I2C accesses are deferred until chip_bus_unlock().

The accesses to the regmap from mcp23s08_probe_one() do not need additional locking.

In all remaining places where the regmap is accessed, except mcp_pinconf_get/set(), the driver already takes mcp->lock.

This patch adds locking in mcp_pinconf_get/set() and disables internal locking in the regmap config. Among other things, it fixes the sleeping in atomic context described above.(CVE-2024-57889)

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

mm/smaps: fix race between smaps_hugetlb_range and migration

smaps_hugetlb_range() handles the pte without holdling ptl, and may be concurrenct with migration, leaing to BUG_ON in pfn_swap_entry_to_page(). The race is as follows.

smaps_hugetlb_range migrate_pages huge_ptep_get remove_migration_ptes folio_unlock pfn_swap_entry_folio BUG_ON

To fix it, hold ptl lock in smaps_hugetlb_range().(CVE-2025-39754)

Severity

5.5 (Medium)

As a result, the system tries to lock the mutex whole holding\nthe spinlock.\n\nIt seems, the internal regmap locks are not needed in this driver at all.\nmcp-\u003elock seems to protect the regmap from concurrent accesses already,\nexcept, probably, in mcp_pinconf_get/set.\n\nmcp23s08_irq_set_type() and mcp23s08_irq_mask/unmask() are called under\nchip_bus_lock(), which calls mcp23s08_irq_bus_lock(). The latter takes\nmcp-\u003elock and enables regmap caching, so that the potentially slow I2C\naccesses are deferred until chip_bus_unlock().\n\nThe accesses to the regmap from mcp23s08_probe_one() do not need additional\nlocking.\n\nIn all remaining places where the regmap is accessed, except\nmcp_pinconf_get/set(), the driver already takes mcp-\u003elock.\n\nThis patch adds locking in mcp_pinconf_get/set() and disables internal\nlocking in the regmap config. Among other things, it fixes the sleeping\nin atomic context described above."

CVE-2025-39754 (GCVE-0-2025-39754)

Vulnerability from cvelistv5 – Published: 2025-09-11 16:52 – Updated: 2026-05-11 21:35

Title

mm/smaps: fix race between smaps_hugetlb_range and migration

Summary

In the Linux kernel, the following vulnerability has been resolved: mm/smaps: fix race between smaps_hugetlb_range and migration smaps_hugetlb_range() handles the pte without holdling ptl, and may be concurrenct with migration, leaing to BUG_ON in pfn_swap_entry_to_page(). The race is as follows. smaps_hugetlb_range migrate_pages huge_ptep_get remove_migration_ptes folio_unlock pfn_swap_entry_folio BUG_ON To fix it, hold ptl lock in smaps_hugetlb_range().

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
