CVE-2021-47511

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: oss: Fix negative period/buffer sizes The period size calculation in OSS layer may receive a negative value as an error, but the code there assumes only the positive values and handle them with sizet. Due to that, a to...

CVE-2021-47509

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: oss: Limit the period size to 16MB Set the practical limit to the period size the fragment shift in OSS instead of a full 31bit; a too large value could lead to the exhaust of memory as we allocate temporary buffers of...

CVE-2021-47511

The CVE-2021-47511 issue affects the Linux kernel ALSA: pcm: oss path, where period size calculation could produce negative values treated as positive due to size_t. The OSS layer could pass an oversized period/buffer to lower layers. The authenticated fix changes handling to ssize_t with proper ...

CVE-2021-47509

CVE-2021-47509 affects the Linux kernel ALSA: pcm: oss, where the period size could be exhaustively allocated due to an overly large 31-bit limit. The fix sets a practical period-size limit of 16 MB to prevent memory exhaustion from temporary OSS buffers. This remediation is reflected in multiple...

SUSE CVE-2021-47332

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y: Don't call freepagesexact with NULL address Unlike some other functions, we can't pass NULL pointer to freepagesexact. Add a proper NULL check for avoiding possible Oops...

CVE-2021-47281

A vulnerability was found in the Linux kernel's ALSA sequencer, where the sndseqtimeropen function fails to properly manage concurrent access to timer instances, which could allow multiple calls to override the timer, leading to a potential use-after-free issue if a timer continues running after...

CVE-2023-52806

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Fix possible null-ptr-deref when assigning a stream While AudioDSP drivers assign streams exclusively of HOST or LINK type, nothing blocks a user to attempt to assign a COUPLED stream. As supplied substream instance ma...
