Daily digests
A use-after-free in the Linux kernel's MPTCP connection lookup code can be triggered over the network. The CVSS is 9.8, but the EPSS score is very low (0.00068, 21st percentile), suggesting real-world exploitation is unlikely right now. Still, kernel-level memory corruption bugs deserve quick attention.
