Remote kernel heap corruption in the illumos SCTP stack lets an unauthenticated attacker send a crafted INIT ACK packet with malformed address parameters to trigger an out-of-bounds access during packet classification, potentially leading to remote code execution or a kernel panic. The flaw affects illumos-gate and downstream distributions (OmniOS, SmartOS/Triton) built before commit 53a3efde, and has existed since 2010 (commit a5407c02). There is no public exploit identified at time of analysis and the CVSS 4.0 exploit-maturity metric is Unreported (E:U), but the attack requires no authentication or user interaction.
Kernel heap corruption in the illumos data-link pseudo-driver (dld) allows an unprivileged local user - including one confined to a non-global zone that owns a datalink - to panic the system or potentially escalate privileges. The flaw in drv_ioc_prop_common() exploits a classic double-copyin TOCTOU race on the DLDIOC_GETMACPROP and DLDIOC_SETMACPROP ioctls: the kernel sizes its heap allocation from pr_valsize on the first copyin but re-reads the entire ioctl struct from the same user address a second time, allowing a concurrent thread to enlarge pr_valsize between the two reads and overflow the under-sized buffer. No public exploit code has been identified and the CVE is not listed in CISA KEV, but the upstream fix is confirmed by an illumos-gate commit.
An issue was discovered in illumos before 2020-10-22, as used in OmniOS before r151030by, r151032ay, and r151034y and SmartOS before 20201022. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.
bhyve, as used in FreeBSD through 12.1 and illumos (e.g., OmniOS CE through r151034 and OpenIndiana through Hipster 2020.04), does not properly restrict VMCS and VMCB read/write operations, as. Rated high severity (CVSS 8.2), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
illumos, as used in OmniOS Community Edition before r151030y, allows a kernel crash via an application with multiple threads calling sendmsg concurrently over a single socket, because. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
