kernel: RDMA/mlx5: Fix error path fall-through in mlx5_ib_dev_res_srq_init()

A flaw was found in the Linux kernel's RDMA/mlx5 component. An error path fall-through in the mlx5ibdevressrqinit function, specifically when ibcreatesrq fails, can lead to the use of freed memory and error pointers. This memory corruption vulnerability could result in system instability, denial ...

kernel: ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()

A flaw was found in the Linux kernel's IPv4 networking component. The ipv4sysctlexitnet function prematurely frees the net-ipv4.sysctllocalreservedports memory. This can lead to a use-after-free vulnerability, where other threads might attempt to access deallocated memory. Such an issue can resul...

kernel: RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()

A flaw was found in the Linux kernel's RDMA/mlx4 component. This vulnerability arises from the incorrect use of Read-Copy Update RCU in the mlx4srqevent function. An attacker could potentially trigger an event before the srq object is fully initialized, leading to a system crash. This could resul...

kernel: io_uring/poll: fix signed comparison in io_poll_get_ownership()

A flaw was found in the Linux kernel's iouring/poll component. A logic error exists in the iopollgetownership function due to an incorrect signed comparison. This flaw prevents the necessary slowpath from being triggered when the IOPOLLCANCELFLAG is set, potentially leading to unexpected behavior...
