CVE-2024-58012

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

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.

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()

Root has patched CVE-2024-58012 in the linux package for Root:Ubuntu:24.04. Multiple fixed versions available.

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

The kernel packages contain the Linux kernel, the core of any Linux operating system.
