sunrpc: potential kernel crash (use after free) in svc_process_common(). (PSBM-73001)
Potential out-of-bounds read in fuse_dev_splice_write(). (PSBM-87649)
It was found that rpc_get_hdr() function from ‘fuse_kio_pcs’ module did not return valid values in ‘msg_size’ in some cases. As a result, the processes using large FUSE KIO messages could get stuck in an unkillable state. (PSBM-87877)
