CVE-2026-46152

CVE-2026-46152 affects the Linux kernel’s wifi/mac80211 subsystem. The root cause is that ieee80211_invoke_fast_rx() uses a static per-invocation rx_result, causing concurrent callers to share a single instance and potentially overwrite results between ieee80211_rx_mesh_data() and the switch on r...

SUSE CVE-2026-46093

In the Linux kernel, the following vulnerability has been resolved: mm/vmalloc: take vmappurgelock in shrinker decayvapoolnode can be invoked concurrently from two paths: purgevmaparealazy when pools are being purged, and the shrinker via vmapnodeshrinkscan. However, decayvapoolnode is not safe t...

CVE-2026-46056

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, exists within the Secure Simple Pairing SSP passkey handlers. It occurs when hciconn lookup and field access are performed without proper locking, allowing a connection to be freed concurrently...
