A flaw was found in the smb client in the Linux kernel. A potential out-of-bounds error was seen in the smb2_parse_contexts function. Validate offsets and lengths before dereferencing create contexts in smb2_parse_contexts. A vulnerability was discovered in the Linux kernel's IPv4 networking stack. Under certain conditions, MPTCP and NetLabel can be configured in a way that triggers a double free memory error in net/ipv4/af_inet.c:inet_sock_destruct. This may lead to a system crash, denial of service, or potential arbitrary code execution. In the Linux kernel, the following vulnerability has been resolved:ext4: regenerate buddy after block freeing failed if under fc replayThis mostly reverts commit 6bd97bf273bd and reintroduces mb_regenerate_buddy. Based oncode in mb_free_blocks, fast commit replay can end up marking as freeblocks that are already marked as such. This causes corruption of thebuddy bitmap so we need to regenerate it in that case
