A memory leak flaw was found in the Linux kernel’s io_uring functionality in how a user registers a buffer ring with IORING_REGISTER_PBUF_RING, mmap() it, and then frees it. This flaw allows a local user to crash or potentially escalate their privileges on the system.
CVE-2024-0582
Score 7.8 from GitHub Security Advisory (severity: HIGH) published 2024-01-16. NVD baseline CVSS 7.8; sources differ by 0.0.
