HID BUFFER OVERFLOW PATCHES LAND IN RC6

By RepoJournal · Filed 06:02 UTC on May 30, 2026 · About Linux

The kernel closes critical buffer overflow vulnerabilities in Lenovo and Wacom HID drivers before the 7.1 release hardens.

Benjamin Tissoires merged a collection of HID fixes that patch buffer overflow issues in the Lenovo and Wacom drivers [1], the kind of vulnerabilities that can corrupt kernel memory if triggered by a malicious or malfunctioning device. The same merge addresses segfault prevention in the Lenovo-Go driver when paired with emulated devices [1], a real-world scenario for testing environments. Separately, the sound subsystem landed a use-after-free fix in the PCM OSS proc interface caught by fuzzer testing [2], a typical but critical kernel stability issue that could crash audio systems under load. On the networking front, an IPv6 address ordering change was reverted after causing SSH connection drops when NetworkManager reconfigures addresses [3], a regression that demonstrates how subtle ordering assumptions break production workloads. The ipsec pull also landed namespace threading fixes for MIGRATE notifications [4] and a sockmap correctness fix for fragment offset calculations in bpf_msg_push_data [5], both addressing edge cases in kernel networking that could cause data corruption or leaks.

Action items

→ Test HID devices after upgrade - buffer overflow fixes require validation torvalds/linux [plan]
→ Monitor SSH connections if using NetworkManager with IPv6 - ordering was reverted torvalds/linux [monitor]
→ Review eBPF sockmap usage - fragment offset fix may affect data layouts torvalds/linux [plan]
