In the Linux kernel, the following vulnerability has been resolved:
sctp: Prevent TOCTOU out-of-bounds write
For the following path not holding the sock lock,
sctp_diag_dump() -> sctp_for_each_endpoint() -> sctp_ep_dump()
make sure not to exceed bounds in case the address list has grown between buffer allocation (time-of-check) and write (time-of-use).
CVSS Details
- CVSS 3.1 Base Score: 7.8
- CVSS 3.1 Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
