kernel: ALSA: seq: midi: Serialize input teardown with event_input

A flaw was found in the Advanced Linux Sound Architecture ALSA MIDI sequencer component of the Linux kernel. A race condition can occur during the teardown of a rawmidi substream while input events are being processed. This can lead to a null pointer dereference, allowing a local attacker to caus...

CVE-2026-98912

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture subsystem. An inverted buffer size check in the OSS Open Sound System sequencer read handler allows a local user to cause memory corruption. Because the kernel checks buffer bounds incorrectly, it copies event data into...

CVE-2026-98912

The Linux kernel contains a vulnerability in the ALSA (Advanced Linux Sound Architecture) seq: oss component within the snd_seq_oss_read() function. The root cause is an inverted check regarding whether a queued OSS sequencer event fits in the remaining userspace buffer. Specifically, the system ...

CVE-2026-98742

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer subsystem. A local user could exploit a race condition caused by missing locking during compatibility ioctl input/output control operations. By sending concurrent port creation requests, an attacker can corrup...

CVE-2026-90220

A flaw was found in the ALSA Advanced Linux Sound Architecture sequencer component of the Linux kernel. An unprivileged local attacker can exploit this vulnerability by sending a specially crafted variable-length event to a non-existent port and then reading the bounced error event. This can lead...

CVE-2026-90207
