There is indeed a mismatch between the size passed to allocator in wilc_wlan_init, and the range of possible indexes used later: allocation size is missing a multiplication by sizeof(u32) Solution(s) ubuntu-upgrade-linux ubuntu-upgrade-linux-aws ubuntu-upgrade-linux-aws-5-15 ubuntu-upgrade-linux-aws-fips ubuntu-upgrade-linux-azure ubuntu-upgrade-linux-azure-5-15 ubuntu-upgrade-linux-azure-fde ubuntu-upgrade-linux-azure-fde-5-15 ubuntu-upgrade-linux-bluefield ubuntu-upgrade-linux-fips ubuntu-upgrade-linux-gcp ubuntu-upgrade-linux-gcp-5-15 ubuntu-upgrade-linux-gcp-fips ubuntu-upgrade-linux-gke ubuntu-upgrade-linux-gkeop ubuntu-upgrade-linux-gkeop-5-15 ubuntu-upgrade-linux-hwe-5-15 ubuntu-upgrade-linux-ibm ubuntu-upgrade-linux-ibm-5-15 ubuntu-upgrade-linux-intel-iot-realtime ubuntu-upgrade-linux-intel-iotg ubuntu-upgrade-linux-intel-iotg-5-15 ubuntu-upgrade-linux-kvm ubuntu-upgrade-linux-lowlatency ubuntu-upgrade-linux-lowlatency-hwe-5-15 ubuntu-upgrade-linux-nvidia ubuntu-upgrade-linux-nvidia-6-5 ubuntu-upgrade-linux-oracle ubuntu-upgrade-linux-oracle-5-15 ubuntu-upgrade-linux-raspi ubuntu-upgrade-linux-realtime ubuntu-upgrade-linux-riscv-5-15 ubuntu-upgrade-linux-xilinx-zynqmp References https://attackerkb.com/topics/cve-2023-52768 CVE - 2023-52768 https://git.kernel.org/linus/05ac1a198a63ad66bf5ae8b7321407c102d40ef3 https://git.kernel.org/stable/c/05ac1a198a63ad66bf5ae8b7321407c102d40ef3 https://git.kernel.org/stable/c/3ce1c2c3999b232258f7aabab311d47dda75605c https://git.kernel.org/stable/c/4b0d6ddb6466d10df878a7787f175a0e4adc3e27 https://git.kernel.org/stable/c/541b3757fd443a68ed8d25968eae511a8275e7c8 https://git.kernel.org/stable/c/6aaf7cd8bdfe245d3c9a8b48fe70c2011965948e https://www.cve.org/CVERecord?id=CVE-2023-52768 View more
