kernel: RDMA/rxe: Fix double free in rxe_srq_from_init

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe driver. An error in the rxesrqfrominit function's memory management can lead to a double free vulnerability. This occurs when an attempt to copy data to user space fails, causing the sam...

kernel: RDMA/vmw_pvrdma: Fix double free on pvrdma_alloc_ucontext() error path

A flaw was found in the Linux kernel, specifically within the RDMA Remote Direct Memory Access vmwpvrdma module. This vulnerability is a double free, which means the system attempts to release the same memory resource twice. This can occur in an error handling path within the pvrdmaallocucontext...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

kernel: RDMA/mana: Validate rx_hash_key_len

A flaw was found in the Linux kernel's RDMA/mana component. A local user could exploit this vulnerability by providing an invalid rxhashkeylen value through a user-space API uAPI structure. This invalid value is then used in a memcpy operation without proper bounds checking, allowing the user to...
