Ubuntu kernel update includes MultiSound driver CVE-2017-9986
Original title: USN-9035-1: Linux kernel vulnerabilities
A local attacker could crash the system or possibly run code via a Turtle Beach audio driver race.
USN-9035-1 says Pengfei Wang found race conditions in the Linux kernel Turtle Beach MultiSound audio driver when fetching from the ring buffer, causing out-of-bounds access. A local attacker could cause a denial of service or possibly execute arbitrary code (CVE-2017-9986). The notice also covers additional kernel flaws in Ethernet bonding, PCI, SCSI, tracing, B.A.T.M.A.N. and IUCV, citing further CVE identifiers.
Unconfirmed: The notice snippet is truncated, so the complete CVE list and fixed versions are not shown.
- CVE-2017-9986 is a local race leading to out-of-bounds access.
- Impact stated is a system crash or possible arbitrary code execution.
- Named additional CVEs include CVE-2022-49114, CVE-2023-52784 and CVE-2024-53194.
- The snippet cuts off the remaining CVE list.

From the original article
Pengfei Wang discovered that the Turtle Beach MultiSound audio device driver in the Linux kernel contained race conditions when fetching from the ring-buffer, leading to an out-of-bounds access. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-9986) Several security issues were discovered in the Linux kernel.
