kernel: tcp: fix skb_copy_ubufs() vs BIG TCP

In the Linux kernel, the following vulnerability has been resolved: tcp: fix skbcopyubufs vs BIG TCP David Ahern reported crashes in skbcopyubufs caused by TCP tx zerocopy using hugepages, and skb length bigger than 68 KB. skbcopyubufs assumed it could copy all payload using up to MAXSKBFRAGS...

kernel: tcp: fix a signed-integer-overflow bug in tcp_add_backlog()

A flaw was found in the Linux kernel’s TCP implementation in the function tcpaddbacklog. When calculating the maximum acceptable backlog for TCP sockets, the sum of the receive buffer skrcvbuf, the send buffer sksndbuf, and a fixed constant may exceed the maximum value of a signed integer due to...

kernel: Linux kernel: Network subsystem memory leak

A flaw was found in the Linux kernel. This vulnerability allows an attacker to cause a denial of service via a memory leak caused by improper handling of skb socket buffer cloning in the network subsystem...

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: fix memory leak in mt7915mcuexit Always purge mcu skb queues in mt7915mcuexit routine even if mt7915firmwarestate fails...

kernel: mptcp: fix UaF in listener shutdown

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix UaF in listener shutdown As reported by Christoph after having refactored the passive socket initialization, the mptcp listener shutdown path is prone to an UaF issue. BUG: KASAN: use-after-free in...

kernel: mptcp: stricter state check in mptcp_worker

A vulnerability was identified in the Linux kernel’s implementation of the Multipath TCP protocol handler. Under certain sequences of socket operations e.g., connecting, resetting/fast-closing, and re-listening, the MPTCP worker could be invoked while the associated master socket is in an...

kernel: nvme-tcp: don't access released socket during error recovery

A race condition leading to NULL pointer dereference was found in the Linux kernel NVMe-over-TCP driver's error recovery handling. A local user with privileges to execute NVMe management commands can run the 'nvme list' command while NVMe-over-TCP error recovery work is temporarily failing...

kernel: Linux kernel: Denial of Service in RDMA/rxe due to null-pointer dereference

A flaw was found in the Linux kernel. A local user could trigger a null-pointer dereference within the Remote Direct Memory Access RDMA subsystem's rxe component. This occurs when a socket creation fails, leading to a system crash and a Denial of Service DoS...
