      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: seq: oss: Reject reads that cannot fit the next event\n\nsnd_seq_oss_read() checks whether the next queued OSS sequencer event\nfits in the remaining userspace buffer before removing it from the read\nqueue.\n\nThe check is inverted. It currently stops when the event is smaller than\nthe remaining buffer, so a normal 4-byte event is not copied for an\n8-byte read buffer. Conversely, an 8-byte event can be copied for a\nsmaller read count.\n\nBreak only when the remaining userspace buffer is smaller than the next\nevent, and report -EINVAL if no complete event has been copied. This\nprevents an undersized read from looking like end-of-file while leaving\nthe event queued for a later read with a large enough buffer.",
