20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: vxlan: vnifilter: Fix unlocked deletion of default FDB entry When a VNI is deleted from a VXLAN device in 'vnifilter' mode, the FDB entry associated with the default remote (assuming one was configured) is deleted without holding the hash lock. This is wrong and will result in a warning [1] being generated by the lockdep annotation that was added by commit ebe642067455 ("vxlan: Create wrappers for FDB lookup").

20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: xsk: Fix race condition in AF_XDP generic RX path Move rx_lock from xsk_socket to xsk_buff_pool. Fix synchronization for shared umem mode in generic RX path where multiple sockets share single xsk_buff_pool. RX queue is exclusive to xsk_socket, while FILL queue can be shared between multiple sockets. This could result in race condition where two CPU cores access RX path of two different sockets sharing the same umem. Protect both queues by ... • https://git.kernel.org/stable/c/bf0bdd1343efbbf65b4d53aef1fce14acbd79d50 •

CVE-2025-37915 – net_sched: drr: Fix double list add in class with netem as child qdisc

20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: net_sched: drr: Fix double list add in class with netem as child qdisc As described in Gerrard's report [1], there are use cases where a netem child qdisc will make the parent qdisc's enqueue callback reentrant. In the case of drr, there won't be a UAF, but the code will add the same classifier to the list twice, which will cause memory corruption. In addition to checking for qlen being zero, this patch checks whether the class was already ... • https://git.kernel.org/stable/c/37d9cf1a3ce35de3df6f7d209bfb1f50cf188cea •

CVE-2025-37905 – firmware: arm_scmi: Balance device refcount when destroying devices

20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Balance device refcount when destroying devices Using device_find_child() to lookup the proper SCMI device to destroy causes an unbalance in device refcount, since device_find_child() calls an implicit get_device(): this, in turns, inhibits the call of the provided release methods upon devices destruction. As a consequence, one of the structures that is not freed properly upon destruction is the internal struct device_pr... • https://git.kernel.org/stable/c/d4f9dddd21f39395c62ea12d3d91239637d4805f •
