kernel: RDMA/core: Fix ib block iterator counter overflow

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix ib block iterator counter overflow When registering a new DMA MR after selecting the best aligned page size for it, we iterate over the given sglist to split each entry to smaller, aligned to the selected page size...

kernel: Linux kernel: Memory leak in RDMA/irdma subsystem leads to Denial of Service

A flaw was found in the Linux kernel's RDMA/irdma subsystem. When the irdma module is unloaded, certain memory objects PBLEs are not properly released, leading to a memory leak. A local attacker could repeatedly trigger this condition, causing system memory to be exhausted and resulting in a Deni...

kernel: SUNRPC: Trap RDMA segment overflows

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Trap RDMA segment overflows Prevent svcrdmabuildwrites from walking off the end of a Write chunk's segment array. Caught with KASAN. The test that this fix replaces is invalid, and might have been left over from an earlie...

kernel: RDMA/core: Make sure "ib_port" is valid when access sysfs node

A NULL pointer dereference flaw was found in the Linux kernel RDMA core's sysfs handling. A local user with access to InfiniBand sysfs nodes can read sysfs attributes while an InfiniBand port is being removed, causing the kernel to dereference a NULL ibport pointer when the port structure has bee...
