CVE-2026-74388

The CVE-2026-74388 issue affects the Linux kernel ALSA: seq: oss component, where SysEx handling in the OSS sequencer could lead to a use-after-free if a sequencer port closes during dispatch. The root cause is a stale pointer in a pending event held after input MIDI bytes are turned into a seque...

CVE-2026-74339 ALSA: seq: Clear variable event pointer on read

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Clear variable event pointer on read sndseqread copies a queued variable-length event header to userspace before expanding the payload. Queued variable-length events use SNDRVSEQEXTCHAINED internally, and data.ext.ptr...

CVE-2026-74339

The CVE-2026-74339 entry describes a Linux kernel ALSA seq vulnerability in snd_seq_read where a queued variable-length event header could reveal a kernel address via data.ext.ptr, because the read path did not clear the temporary header pointer before copy_to_user. The fix involves clearing that...

CVE-2026-74278 ALSA: seq: Fix kernel heap address leak in bounce_error_event()

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Fix kernel heap address leak in bounceerrorevent The comment above bounceerrorevent documents that user clients should receive SNDRVSEQEVENTBOUNCE with the original event embedded as variable-length data, while kernel...

CVE-2026-74278

CVE-2026-74278 affects the Linux kernel ALSA seq subsystem. The leak arises from bounce_error_event() always emitting SNDRV_SEQ_EVENT_KERNEL_ERROR with a raw struct snd_seq_event pointer exposed to users. The fix differentiates by client type: for USER_CLIENTS, send SNDRV_SEQ_EVENT_BOUNCE with SN...
