26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: NFSv4.2: fix reference count leaks in _nfs42_proc_copy_notify() [You don't often get email from xiongx18@fudan.edu.cn. Learn why this is important at http://aka.ms/LearnAboutSenderIdentification.] The reference counting issue happens in two error paths in the function _nfs42_proc_copy_notify(). In both error paths, the function simply returns the error code and forgets to balance the refcount of object `ctx`, bumped by get_nfs_open_context(... • https://git.kernel.org/stable/c/9b9feec97c1fc7dd9bb69f62c4905cddf1801599 •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix leak of nested actions While parsing user-provided actions, openvswitch module may dynamically allocate memory and store pointers in the internal copy of the actions. So this memory has to be freed while destroying the actions. Currently there are only two such actions: ct() and set(). However, there are many actions that can hold nested lists of actions and ovs_nla_free_flow_actions() just jumps over them leaking the ... • https://git.kernel.org/stable/c/34ae932a40369be6bd6ea97d66b6686361b4370d •
