CVE-2022-49669 – mptcp: fix race on unaccepted mptcp sockets
https://notcve.org/view.php?id=CVE-2022-49669
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: mptcp: fix race on unaccepted mptcp sockets When the listener socket owning the relevant request is closed, it frees the unaccepted subflows and that causes later deletion of the paired MPTCP sockets. The mptcp socket's worker can run in the time interval between such delete operations. When that happens, any access to msk->first will cause an UaF access, as the subflow cleanup did not cleared such field in the mptcp socket.

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: can: gs_usb: gs_usb_open/close(): fix memory leak The gs_usb driver appears to suffer from a malady common to many USB CAN adapter drivers in that it performs usb_alloc_coherent() to allocate a number of USB request blocks (URBs) for RX, and then later relies on usb_kill_anchored_urbs() to free them, but this doesn't actually free them. As a result, this may be leaking DMA memory that's been used by the driver. This commit is an adaptation ... • https://git.kernel.org/stable/c/d08e973a77d128b25e01a08c34d89593fdf222da •
