CVE-2025-68251

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

ptr_ring: do not block hard interrupts in ptr_ring_resize_multiple()

Jakub added a lockdep_assert_no_hardirq() check in __page_pool_put_page() to increase test coverage.

syzbot found a splat caused by hard irq blocking in ptr_ring_resize_multiple() [1]

As current users of ptr_ring_resize_multiple() do not require hard irqs being masked, replace it to only block BH.

Rename helpers to better reflect they are safe against BH only.

• ptr_ring_resize_multiple() to ptr_ring_resize_multiple_bh()
• skb_array_resize_multiple() to skb_array_resize_multiple_bh()

ASoC: SOF: Intel: hda-dai: Ensure DAI widget is valid during params

Each cpu DAI should associate with a widget. However, the topology might not create the right number of DAI widgets for aggregated amps. And it will cause NULL pointer deference. Check that the DAI widget associated with the CPU DAI is valid to prevent NULL pointer deference due to missing DAI widgets in topologies with aggregated amps.(CVE-2024-58012)

driver core: fix potential NULL pointer dereference in dev_uevent()

If userspace reads "uevent" device attribute at the same time as another threads unbinds the device from its driver, change to dev->driver from a valid pointer to NULL may result in crash. Fix this by using READ_ONCE() when fetching the pointer, and take bus' drivers klist lock to make sure driver instance will not disappear while we access it.

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

erofs: avoid infinite loops due to corrupted subpage compact indexes

Robert reported an infinite loop observed by two crafted images.

The root cause is that clusterofs can be larger than lclustersize for !NONHEAD lclusters in corrupted subpage compact indexes, e.g.:

blocksize = lclustersize = 512 lcn = 6 clusterofs = 515

Move the corresponding check for full compress indexes to z_erofs_load_lcluster_from_disk() to also cover subpage compact compress indexes.

It also fixes the position of m->type >= Z_EROFS_LCLUSTER_TYPE_MAX check, since it should be placed right after z_erofs_load_{compact,full}_lcluster().
