https://notcve.org/view.php?id=CVE-2021-47132
15 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: mptcp: fix sk_forward_memory corruption on retransmission MPTCP sk_forward_memory handling is a bit special, as such field is protected by the msk socket spin_lock, instead of the plain socket lock. Currently we have a code path updating such field without handling the relevant lock: __mptcp_retrans() -> __mptcp_clean_una_wakeup() Several helpers in __mptcp_clean_una_wakeup() will update sk_forward_alloc, possibly causing such field corrupt... • https://git.kernel.org/stable/c/64b9cea7a0afe579dd2682f1f1c04f2e4e72fd25 •

15 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: net/tls: Fix use-after-free after the TLS device goes down and up When a netdev with active TLS offload goes down, tls_device_down is called to stop the offload and tear down the TLS context. However, the socket stays alive, and it still points to the TLS context, which is now deallocated. If a netdev goes up, while the connection is still active, and the data flow resumes after a number of TCP retransmissions, it will lead to a use-after-f... • https://git.kernel.org/stable/c/e8f69799810c32dd40c6724d829eccc70baad07f •

15 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: nvmet: fix freeing unallocated p2pmem In case p2p device was found but the p2p pool is empty, the nvme target is still trying to free the sgl from the p2p pool instead of the regular sgl pool and causing a crash (BUG() is called). Instead, assign the p2p_dev for the request only if it was allocated from p2p pool.
