CVE-2024-41062

CVE-2024-41062 concerns the Linux kernel Bluetooth L2CAP path where a race can occur between sock_close releasing a socket and hci_rx_work accessing it. The root cause is a lack of lock protection around the socket during the transition, potentially allowing hci_rx_work to touch a freed sock. The...

CVE-2024-41062 bluetooth/l2cap: sync sock recv cb and release

In the Linux kernel, the following vulnerability has been resolved: bluetooth/l2cap: sync sock recv cb and release The problem occurs between the system call to close the sock and hcirxwork, where the former releases the sock and the latter accesses it without lock protection.

The vulnerability of the reqsk_queue_alloc() function in the Linux kernel-based TCP protocol implementation allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the reqskqueuealloc function in the net/core/requestsock.c module of the Linux kernel’s TCP protocol implementation is related to deficiencies in the serialization mechanism, leading to competitive access to resources. Exploiting this vulnerability could allow a remote attack...

CVE-2021-47294

A vulnerability was found in the Linux kernel's NetRom subsystem. This issue arises when socket timers expire, if the timer handler does not decrease the socket reference count as needed, the socket reference count becomes unbalanced. This can result in the socket not being freed properly,...
