kernel: crypto: af_alg - limit RX SG extraction by receive buffer budget

A flaw was found in the Linux kernel's afalg Algorithm Interface component. This vulnerability allows a local attacker to cause a denial of service DoS by sending specially crafted requests. The afalggetrsgl function fails to properly limit the extraction of receive scatterlist RX SG data based o...

kernel: Linux kernel: Denial of service and memory corruption in RDMA umad

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA umad User Mode Access Device component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denia...
