kernel: Bluetooth: hci_conn: Fix UAF in hci_enhanced_setup_sync
A flaw was found in the Linux kernel's Bluetooth subsystem. When an Asynchronous Connection-Less ACL connection is destroyed while the hcienhancedsetupsync function is processing a command, it can lead to a use-after-free UAF condition. An adjacent attacker could exploit this vulnerability to cau...
kernel: Bluetooth: ISO: Fix not validating setsockopt user input
CVE-2024-35964 is a vulnerability in the Linux kernel’s Bluetooth ISO implementation. It occurs because the setsockopt function does not properly validate the size of user-provided data before copying it into kernel memory. This flaw can lead to buffer overflows, potentially resulting in crashes ...
kernel: Bluetooth: L2CAP: Fix not validating setsockopt user input
CVE-2024-35965 is a vulnerability in the Linux kernel's Bluetooth L2CAP implementation, caused by inadequate input length validation in the setsockopt function. This flaw allows overly large user-provided data to be copied into kernel memory, potentially leading to buffer overflows, system...
kernel: Bluetooth: Fix memory leak in hci_req_sync_complete()
This CVE identifies a memory leak in the Linux kernel's Bluetooth subsystem, specifically within the hcireqsynccomplete function. The issue arises because the function fails to release the previous synchronization request state before assigning a new one, leading to increased memory usage over...
