Answer in brief
CVE-2026-98912 records a Unknown severity vulnerability in ALSA: seq: oss: Reject reads that cannot fit the next event. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: oss: Reject reads that cannot fit the next event snd_seq_oss_read() checks whether the next queued OSS sequencer event fits in the remaining userspace buffer before removing it from the read queue. The check is inverted. It currently stops when the event is smaller than the remaining buffer, so a normal 4-byte event is not copied for an 8-byte read buffer. Conversely, an 8-byte event can be copied for a smaller read count. Break only when the remaining userspace buffer is smaller than the next event, and report -EINVAL if no complete event has been copied. This prevents an undersized read from looking like end-of-file while leaving the event queued for a later read with a large enough buffer.
