It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code.

An out-of-bounds memory access flaw was found in the io_uring SQ/CQ rings functionality in the Linux kernel. This issue could allow a local user to crash the system.
