CVE-2022-49538

In the Linux kernel, the following vulnerability has been resolved: ALSA: jack: Access inputdev under mutex It is possible when using ASoC that inputdev is unregistered while calling sndjackreport, which causes NULL pointer dereference. In order to prevent this serialize access to inputdev using...

CVE-2022-49291

The CVE-2022-49291 entry describes a Linux kernel flaw in ALSA: pcm where concurrent hw_params and hw_free ioctls could trigger a use-after-free. The fix introduces a dedicated mutex (runtime->buffer_mutex) and applies it to both hw_params and hw_free code paths, with small reordering (mmap_co...

CVE-2022-49291

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix races among concurrent hwparams and hwfree calls Currently we have neither proper check nor protection against the concurrent calls of PCM hwparams and hwfree ioctls, which may result in a UAF. Since the existing P...

CVE-2022-49288 ALSA: pcm: Fix races among concurrent prealloc proc writes

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix races among concurrent prealloc proc writes We have no protection against concurrent PCM buffer preallocation changes via proc files, and it may potentially lead to UAF or some weird problem. This patch applies the...

CVE-2024-57800

In the Linux kernel, the following vulnerability has been resolved: ALSA: memalloc: prefer dmamappingerror over explicit address checking With CONFIGDMAAPIDEBUG enabled, the following warning is observed: DMA-API: sndhdaintel 0000:03:00.1: device driver failed to check map errordevice...

CVE-2024-57800 ALSA: memalloc: prefer dma_mapping_error() over explicit address checking

In the Linux kernel, the following vulnerability has been resolved: ALSA: memalloc: prefer dmamappingerror over explicit address checking With CONFIGDMAAPIDEBUG enabled, the following warning is observed: DMA-API: sndhdaintel 0000:03:00.1: device driver failed to check map errordevice...

CVE-2024-57800

CVE-2024-57800 affects the Linux kernel in ALSA memalloc handling. When DMA API debugging is enabled, it may warn about a device driver failing to check a DMA address map, e.g. device address 0x00000000ffff0000, due to explicit address checks instead of using dma_mapping_error(). The documented f...

CVE-2024-53180

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Add sanity NULL check for the default mmap fault handler A driver might allow the mmap access before initializing its runtime-dmaarea properly. Add a proper NULL check before passing to virttopage for avoiding a panic...

CVE-2024-56533

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y: Use sndcardfreewhenclosed at disconnection The USB disconnect callback is supposed to be short and not too-long waiting. OTOH, the current code uses sndcardfree at disconnection, but this waits for the close of all...

CVE-2024-56533

The CVE-2024-56533 vulnerability affects the Linux kernel’s ALSA usx2y driver. It stems from using snd_card_free() during USB disconnection, which waits for all open fds to close and can delay release, potentially blocking USB IOCTLs and causing a soft lockup. The advisory notes replacing snd_car...
