https://notcve.org/view.php?id=CVE-2022-49212
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_init The reference counting issue happens in several error handling paths on a refcounted object "nc->dmac". In these paths, the function simply returns the error code, forgetting to balance the reference count of "nc->dmac", increased earlier by dma_request_channel(), which may cause refcount leaks. Fix it by decrementing the refcount of specific object in those error paths. • https://git.kernel.org/stable/c/f88fc122cc34c2545dec9562eaab121494e401ef •

CVE-2022-49209 – bpf, sockmap: Fix memleak in tcp_bpf_sendmsg while sk msg is full

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix memleak in tcp_bpf_sendmsg while sk msg is full If tcp_bpf_sendmsg() is running while sk msg is full. When sk_msg_alloc() returns -ENOMEM error, tcp_bpf_sendmsg() goes to wait_for_memory. If partial memory has been alloced by sk_msg_alloc(), that is, msg_tx->sg.size is greater than osize after sk_msg_alloc(), memleak occurs. To fix we use sk_msg_trim() to release the allocated memory, then goto wait for memory. Other call ... • https://git.kernel.org/stable/c/604326b41a6fb9b4a78b6179335decee0365cd8c •
