CVE-2021-41229 – Memory leak in BlueZ
https://notcve.org/view.php?id=CVE-2021-41229
BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in sdp_cstate_alloc_buf which allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object, which can be caused by an attacker continuously sending sdp packets and this may cause the service of the target device to crash. BlueZ es una pila de protocolos Bluetooth para Linux. • https://github.com/bluez/bluez/security/advisories/GHSA-3fqg-r8j5-f5xq https://lists.debian.org/debian-lts-announce/2021/11/msg00022.html https://lists.debian.org/debian-lts-announce/2022/10/msg00026.html https://security.netapp.com/advisory/ntap-20211203-0004 https://access.redhat.com/security/cve/CVE-2021-41229 https://bugzilla.redhat.com/show_bug.cgi?id=2025034 • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
