Illumos Gate
Monthly
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.
illumos illumos-gate before 676abcb has a stack buffer overflow in /dev/net, leading to privilege escalation via a stat on a long file name in /dev/net. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
