About this tag
CVE-2024-27053 is a high-severity vulnerability in the Linux kernel's WILC1000 Wi-Fi driver, involving improper use of Read-Copy-Update (RCU) primitives. The flaw can cause denial of service and, under specific race conditions, potential memory corruption. It arises from dereferencing an RCU-protected pointer outside the critical section during Wi-Fi connection handling. Upstream patches fix this by narrowing the RCU-protected window to only the minimal work needed for safely copying information elements. Systems using the vulnerable wilc1000 driver should apply updates to mitigate the risk.
