In the Linux kernel, the following vulnerability has been resolved: net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc() syzbot found hanging tasks waiting on rtnl_lock [1] A reproducer is available in the syzbot bug. When a request to add multiple actions with the same index is sent, the second request will block forever on the first request. This holds rtnl_lock, and causes tasks to hang. Return -EAGAIN to prevent infinite looping, while keeping documented behavior. [1] INFO: task kworker/1:0:5088 blocked for more than 143 seconds.

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: Fix suspicious rcu_dereference_protected() When destroying all sets, we are either in pernet exit phase or are executing a "destroy all sets command" from userspace. The latter was taken into account in ip_set_dereference() (nfnetlink mutex is held), but the former was not. The patch adds the required check to rcu_dereference_protected() in ip_set_dereference(). • https://git.kernel.org/stable/c/390b353d1a1da3e9c6c0fd14fe650d69063c95d6 https://git.kernel.org/stable/c/2ba35b37f780c6410bb4bba9c3072596d8576702 https://git.kernel.org/stable/c/90ae20d47de602198eb69e6cd7a3db3420abfc08 https://git.kernel.org/stable/c/788d585e62f487bc4536d454937f737b70d39a33 https://git.kernel.org/stable/c/94dd411c18d7fff9e411555d5c662d29416501e4 https://git.kernel.org/stable/c/3fc09e1ca854bc234e007a56e0f7431f5e2defb5 https://git.kernel.org/stable/c/3799d02ae4208af08e81310770d8754863a246a1 https://git.kernel.org/stable/c/72d9611968867cc4c5509e7708b1507d6 •

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix responder length checking for UD request packets According to the IBA specification: If a UD request packet is detected with an invalid length, the request shall be an invalid request and it shall be silently dropped by the responder. The responder then waits for a new request packet. commit 689c5421bfe0 ("RDMA/rxe: Fix incorrect responder length checking") defers responder length check for UD QPs in function `copy_data`. But it introduces a regression issue for UD QPs. When the packet size is too large to fit in the receive buffer. `copy_data` will return error code -EINVAL. Then `send_data_in` will return RESPST_ERR_MALFORMED_WQE. UD QP will transfer into ERROR state. • https://git.kernel.org/stable/c/689c5421bfe0eac65526bd97a466b9590a6aad3c https://git.kernel.org/stable/c/163868ec1f6c610d16da9e458fe1dd7d5de97341 https://git.kernel.org/stable/c/943c94f41dfe36536dc9aaa12c9efdf548ceb996 https://git.kernel.org/stable/c/f67ac0061c7614c1548963d3ef1ee1606efd8636 •
