25 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: bpf: Check validity of link->type in bpf_link_show_fdinfo() If a newly-added link type doesn't invoke BPF_LINK_TYPE(), accessing bpf_link_type_strs[link->type] may result in an out-of-bounds access. To spot such missed invocations early in the future, checking the validity of link->type in bpf_link_show_fdinfo() and emitting a warning when such invocations are missed. • https://git.kernel.org/stable/c/4e8074bb33d18f56af30a0252cb3606d27eb1c13 •

21 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: smb: client: Fix use-after-free of network namespace. Recently, we got a customer report that CIFS triggers oops while reconnecting to a server. [0] The workload runs on Kubernetes, and some pods mount CIFS servers in non-root network namespaces. The problem rarely happened, but it was always while the pod was dying. The root cause is wrong reference counting for network namespace. CIFS uses kernel sockets, which do not hold refcnt o... • https://git.kernel.org/stable/c/26abe14379f8e2fa3fd1bcf97c9a7ad9364886fe • CWE-416: Use After Free •

21 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Add sendpage_ok() check to disable MSG_SPLICE_PAGES While running ISER over SIW, the initiator machine encounters a warning from skb_splice_from_iter() indicating that a slab page is being used in send_page. To address this, it is better to add a sendpage_ok() check within the driver itself, and if it returns 0, then MSG_SPLICE_PAGES flag should be disabled before entering the network stack. A similar issue has been discussed f... • https://git.kernel.org/stable/c/3406bfc813a9bbd9c3055795e985f527b7852e8c •

21 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: nvme-multipath: defer partition scanning We need to suppress the partition scan from occuring within the controller's scan_work context. If a path error occurs here, the IO will wait until a path becomes available or all paths are torn down, but that action also occurs within scan_work, so it would deadlock. Defer the partion scan to a different context that does not block scan_work. • https://git.kernel.org/stable/c/60de2e03f984cfbcdc12fa552f95087c35a05a98 •

21 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: afs: Fix lock recursion afs_wake_up_async_call() can incur lock recursion. The problem is that it is called from AF_RXRPC whilst holding the ->notify_lock, but it tries to take a ref on the afs_call struct in order to pass it to a work queue - but if the afs_call is already queued, we then have an extraneous ref that must be put... calling afs_put_call() may call back down into AF_RXRPC through rxrpc_kernel_shutdown_call(), however, whic... • https://git.kernel.org/stable/c/d7cbf81df996b1eae2dee8deb6df08e2eba78661 •

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: prevent the risk of out of memory access The dvbdev contains a static variable used to store dvb minors. The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set or not. When not set, dvb_register_device() won't check for boundaries, as it will rely that a previous call to dvb_register_adapter() would already be enforcing it. On a similar way, dvb_device_open() uses the assumption that the register functions already... • https://git.kernel.org/stable/c/5dd3f3071070f5a306bdf8d474c80062f5691cba •

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: media: s5p-jpeg: prevent buffer overflows The current logic allows word to be less than 2. If this happens, there will be buffer overflows, as reported by smatch. Add extra checks to prevent it. While here, remove an unused word = 0 assignment. • https://git.kernel.org/stable/c/6c96dbbc2aa9f5b4aed8792989d69eae22bf77c4 •

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT In qdisc_tree_reduce_backlog, Qdiscs with major handle ffff: are assumed to be either root or ingress. This assumption is bogus since it's valid to create egress qdiscs with major handle ffff: Budimir Markovic found that for qdiscs like DRR that maintain an active class list, it will cause a UAF with a dangling class pointer. In 066a3b5b2346, the concern was to avoid iterating over t... • https://git.kernel.org/stable/c/066a3b5b2346febf9a655b444567b7138e3bb939 • CWE-416: Use After Free •

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: io_uring/rw: fix missing NOWAIT check for O_DIRECT start write When io_uring starts a write, it'll call kiocb_start_write() to bump the super block rwsem, preventing any freezes from happening while that write is in-flight. The freeze side will grab that rwsem for writing, excluding any new writers from happening and waiting for existing writes to finish. But io_uring unconditionally uses kiocb_start_write(), which will block if someone i... • https://git.kernel.org/stable/c/485d9232112b17f389b29497ff41b97b3189546b •
